Changelog: [Internal][iOS] Minor: Rename RCTNotAllowedInAppWideFabric to RCTNotAllowedInFabricWithoutLegacy
`RCTNewArchitectureValidationPlaceholder(RCTNotAllowedInBridgeless` is to track Bridge APIs that are okay in Fabric but not in Bridgeless.
`RCTNewArchitectureValidationPlaceholder(RCTNotAllowedInFabricWithoutLegacy` is to track legacy APIs that should not exist if the app was using Fabric **without any legacy architecture**. e.g. RCTBridgeModule, legacy interop view components.

Changelog: [Internal]
- Make the new architecture validation easier to understand by enabling validation with `RCTNewArchitectureSetMinValidationLevel(level)`.
- When `RCT_ONLY_NEW_ARCHITECTURE` flag is enabled:
- `RCTErrorNewArchitectureValidation` calls `RCTLogAssert` instead of `RCTLogError`.
- `RCTNewArchitectureValidationPlaceholder` calls `RCTLog`, instead of no-op.

Summary:
Changelog:
[iOS][Fixed] - Expose the extraData dict attached to JavaScript errors to the native ExceptionManager on iOS, similar to Android
Attaching the `extraData` dict to JavaScript crash reports is something that was done for Android only in 2019 (D16133080 (3a825c0360)), and somehow we never really got around to adding it in iOS. This diff finally adds the capability to iOS as well. `extraData` can be used to attach various bits of data to a crash report for better debugging and categorization. As with the Android implementation, `extraData` is not attached if the `reportException` API is not used.

Summary:
Changelog: [iOS][Internal] Add api to disable New validation reporting
Previously `RCTNewArchitectureValidationSetEnabled` was not set to false once it was set to true when a use is in app-wide Bridgeless mode.
This resulted it being in an incorrect state if a user:
1) Opens RN while in app-wide Bridgeless enabled
2) Logout
3) Re-login as another user without killing the app.
The fix is to set `RCTNewArchitectureValidationSetEnabled(RCTNotAllowedValidationDisabled)` in FBReactModule initialization.

Summary:
Changelog: [Internal][iOS] Add validation reporting APIs for unexpected uses of Paper when Fabric is enabled
## RCTNotAllowedInBridgeless
Previously, we only had violation reporting APIs for when **Bridge APIs** are used in **Bridgeless mode**, which was only enabled in Bridgeless mode.
## RCTNotAllowedInFabric
This diff adds violation reporting APIs to use when **pre-Fabric Bridge APIs** are used in **Bridge or Bridgeless mode**. This allows us to add RCTAssert/RCTError/RCTLog to more APIs in Bridge mode. The main purpose is to distinguish between Bridge APIs that still work in Fabric, versus Bridge APIs that are no longer used in Fabric, so that the latter can be removed.

Summary:
To prepare for the new architecture, introduce the following enforcement:
* Defining `RCT_NEW_ARCHITECTURE` in the build flag automatically enables violation reporting
* At runtime, call RCTEnableNewArchitectureViolationReporting() to enable/disable reporting - it takes effect with the future violations
* When violation reporting is enabled:
* RCTWarnNotAllowedForNewArchitecture(): log warning about a violation, but doesn't assert
* RCTEnforceNotAllowedForNewArchitecture(): assert when a violation happen
Also in this commit:
* Add warning when RCTRegisterModule() is called as a side effect of RCT_EXPORT_MODULE(). Many modules still need this, so we can't enforce it yet.
* Add enforcement when the bridge is initialize, because the new architecture cannot have the bridge.

Summary:
In order to move away from the legacy system (bridge etc), we need to decouple the new architecture assumptions from it. This flag and assertion functions will help track the runtime and report violations along the way. The goal is to have 0 violation before switching over to the pure new architecture.
Note: this is not used right now.

Summary:
When we catch an Objective-C exception and convert it to NSError we need to somehow represent the call stack from NSException instance in NSError instance. For now, we just attach the stack trace to `message` field.
The next step would be to figure out how to pass the Objective-C stack trace to error reporting infra to help it to display the stack trace nicely in the web interface.

Summary:
<!-- Explain the **motivation** for making this change. What existing problem does the pull request solve? -->
I have used RN for a long time, and for all this time, crash reporting has been less great than native development crash reporting. At some point, companies like sentry, bugsnag and a bunch of others started supporting sourcemaps for js crashes in RN, which helped a lot.
But native crashes were (and still are) much harder to diagnose.
..Until now :D
I have make a repo of a sample RN app, included this PR in it, and some code and screenshots to help.
The repo is [here](https://github.com/pvinis/react-native-project-with-crash-heaven-pr).
I was trying to get good crash reports from native crashes in iOS for a looong time. I spoke with people in sentry, in bugsnag and more, and I could not get this solved. There was no clear way to get the **native** crashed to display correctly.
I made two repos here, one for [sentry](https://github.com/pvinis/SentryBadStack) and one for [bugsnag](https://github.com/pvinis/BugsnagBadStack), demonstrating the correct js handling and the bad native handling.
After all this, and talks with their support, twitter etc, I investigated further, on **why** this was happening. I thought there must be some reason that native crashes look bad in all the tools, and in the same way. Maybe it's not their fault, or up to them to fix it, or maybe they didn't have the experience to fix it.
In a test project I created, I checked what's up with the `RCTFatalException`, and I found out that the React Native code is catching the `NSException`s that come from any native modules of a RN app and converting it into an string and sending it to `RCTFatal` that created an `NSError` out of that string. Then it checks if the app has set a fatal error handler and if not, goes ahead and throws that `NSError`.
The problem here is that `NSException` has a bunch more info that the resulting `NSError` is missing or is altering. Turning the callstack into a string renders crash reporting tools useless as they are missing the original place the exception was thrown, symbols, return addresses etc. In both repos above it can be seen that both tools were thinking that the error happened somewhere in the `RCTFatal` function, and it did, since we create it there, losing all the previous useful info of the original exception. That leaves us with just a very long name including a callstack, but very hard to actually map this to the code and dsym.
I added a fatal exception handler, that mirrors the fatal error handler, as the error handler is used around React Native internal code.
Then I stopped making a string out of the original `NSException` and calling `RCTFatal`, and I simply throw the exception. This way no info is lost!
Finally, I added some code examples of native and js crashes and added a part in the `RNTester` app, so people can see how a js and a native error look like while debugging, as well as try to compile the app in release mode and see how the crash report would look like if they connect it to bugsnag or sentry or their tool of choice.
I have attached some images at the bottom of this PR, and you can find some in the 3 repos I linked above.
[iOS] [Fixed] - Changed the way iOS native module exceptions get handled. Instead of making them into an `NSError` and lose the context and callstack, we keep them as `NSException`s and propagate them.
[General] [Added] - Example code for native crashes in iOS and Android, with buttons on RNTester, so developers can see how these look when debugging, as well as the crash reports in release mode.

Summary:
Fixes#22530
As described in the issue, the previous behavior for the `RCTFatal` macro was to truncate the `reason` on the resulting `NSException` to 75 characters. This would ensure the reason would fit on a single line, but resulted in issues debugging errors that occurred in the wild, as many crash logging tools (like Sentry) discard the `name` value of the exception and use the `reason` as their primary identifier. At 75 characters, useful information like the location of the error would usually be truncated.
- [x] This extends the truncation threshold to 175 characters, which should be short enough to prevent full-screen-takeover length errors, but long enough to provide useful context to the error.
- [x] This adds a `userInfo` value to the resulting `NSException`. It copies over the `userInfo` from the `NSError` passed to the macro, and adds an "untruncated message" value that contains the untruncated version of the `NSException`'s reason.
[iOS] [Changed] - RCTFatalExceptions now include more information in their reason and a userInfo.

Summary:
As per https://twitter.com/olebegemann/status/738656134731599872, our use of "main thread" to mean "main queue" seems to be unsafe.
This diff replaces the `NSThread.isMainQueue` checks with dispatch_get_specific(), which is the recommended approach.
I've also replaced all use of "MainThread" terminology with "MainQueue", and taken the opportunity to deprecate the "sync" param of `RCTExecuteOnMainThread()`, which, while we do still use it in a few places, is incredibly unsafe and shouldn't be encouraged.

Summary: public
Add RCTFatal for reporting fatal runtime conditions. This centralizes failure handling to one function and allows you to customize how they should be handled. RCTFatal will be logged to the console and as a redbox and will also be triggered by fatal exceptions coming from RCTExceptionsManager.
Note that there is no RCTLogFatal, since just logging the fatal condition does not allow us to handle it consistently.

Summary:
I encountered a crash when `RCTCurrentThreadName` called `dispatch_get_current_queue`. There are reports of it crashing e.g. https://github.com/CocoaLumberjack/CocoaLumberjack/issues/108 so better not to call it at all, plus it is deprecated.
Since we still want helpful debugging information, use `DISPATCH_CURRENT_QUEUE_LABEL` instead. It's kind of strange that this constant is defined to be NULL and the docs for `dispatch_get_queue_label` say not to pass in NULL, but in practice `DISPATCH_CURRENT_QUEUE_LABEL` is provided by the iOS SDK and works correctly.

Summary:
@public
I've increased the warning levels in the OSS frameworks, which caught a bunch of minor issues. I also fixed some new errors in Xcode 7 relating to designated initializers and TLS security.
Test Plan:
* Test the sample apps and make sure they still work.
* Run tests.
Summary:
@public
Add `RCTAssertThread` to `RCTAssert.h` for convenience when checking the current/queue,
it accepts either a `NSString *`, `NSThread *` or `dispatch_queue_t` as the object to be checked
Also add a check to `-[RCTUIManager addUIBlock:]` - There was a discussion on github (https://github.com/facebook/react-native/issues/1365)
due to the weird behavior caused by calling it from a different thread/queue (it might be added after `batchDidComplete` has been called
and will just be dispatched on the next call from JS to objc)
Test Plan:
Change `-[RCTAnimationExperimentalManager methodQueue]` to return `dispatch_get_main_queue()` and run the 2048 example,
it should dispatch with a helpful message (screenshot on the comments)
