Notably, this adds support for TypeScript 3.8,
which introduces new syntax, such as `import type`.

Summary:
In heap snapshots, it was found that really large (20 MB) strings representing network data
were being logged as part of `Systrace.beginEvent` strings from `MessageQueue` in DEV mode.
To combat this, use `JSON.stringify` with limits to keep the depth, strings, arrays, and objects
in check.

Summary:
I happened to hit this error a couple times and the issue is that if there are let's say 1000 pending callbacks the error would be triggered 500 times and pretty much crash the app. I think it is reasonable to use warn once here so it only happens once.
## Changelog
[General] [Fixed] - Use `warnOnce` for excessive number of callbacks error
Pull Request resolved: https://github.com/facebook/react-native/pull/26508
Test Plan: Tested by reducing the number of pending callbacks required to trigger the error.

Summary:
We've seen some crashes from exceeding property limits (>200k) from storing callbacks, which is insane since callbacks should be called and cleaned up right away in most cases. Browsing around I never see more than about 50 pending callbacks when firing off a whole much of animations and measures and stuff.
In order to track down the leak, I added some code in `__DEV__` to provide more info - hopefully some developers will hit it and report the issue. Unfortunately it's not easy to get any useful information in prod because we strip all the useful debug info, but if this continues to be a problem we could try capturing that info in prod as well (and maybe other info, too).

Summary:
When a synchronous call from JS to native code throws an error, it doesn't include a useful stack trace from the native side. To improve error attribution, this diff pops the frames in `MessageQueue.js` and `NativeModules.js` from the stack traces of such errors. This uses the `error.framesToPop` convention understood by RN's global error handler.
For now we limit this to errors converted from C++ exceptions in host functions, since those are not likely to ever contain further JavaScript frames at the point where we catch them; if they did, it would violate our assumption that the top two frames of the stack are in the JS bridge code.

Summary:
Types the last 3 members of the `ModuleConfig` tuple (functions, promise method IDs, and sync method IDs) as nullable and immutable arrays. This is in line with how they are used in the code; one debug-only call site had to be fixed to account for nullability.
Also updates the test data in `MessageQueueTestConfig` to explicitly conform to this type.

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.
See the umbrella issue at https://github.com/facebook/react-native/issues/24316 for more detail.

Summary:
We need to move animated native module calls to synchronous so we can properly thread them in with mounting instructions in Fabric. Some of them take callbacks so we need to add support for that when switching to synchronous.
A side benefit is that we can unify codepaths a little more with async callbacks.

Summary:
`new Date().getTime()` is equal to `Date.now()`.
`Date.now()` avoids an allocation, which can save some GC time.
This micro-optimization isn't worth it in most places, but since MessageQueue is one of the hottest pieces of JS in RN, it's worth it.

NaN is not handled consistently by the bridge in all cases,

Summary:
This makes JSTimers actively register a callback for callImmediates.
Besides being generally tricky, circular dependency prevent compiling React Native code with bundlers that rely on concatenating module sources rather that evaluating code at the time of requiring, like Google Closure Compiler.
Sadly, Google Closure Compiler setup that prompted this change is complicated and brittle. And there are no good public tools to find circular dependencies among Haste-style modules (with unqualified require paths).
So some advice on a good test plan would be useful. Does Facebook have any tools to find circular dependencies with Haste-style requires?
FWIW, a check that worked for me was to replace all import paths in React Native from Haste style to normal relative paths (which I needed anyway) and then run [`madge`](https://www.npmjs.com/package/madge) on the code base:
```
$ ~/node_modules/.bin/madge --circular react-native/Libraries
Processed 390 files (7.4s) (81 warnings)
✖ Found 2 circular dependencies!
1) BatchedBridge/NativeModules.js > BatchedBridge/BatchedBridge.js > BatchedBridge/MessageQueue.js > Core/Timers/JSTimers.js
2) StyleSheet/flattenStyle.js > StyleSheet/StyleSheet.js
```
(The second cycle is already eliminated in a8e3c7f578).
[GENERAL] [MINOR] [MessageQueue] - MessageQueue implementation doesn't have a circular dependency on JSTimers.

It configures Flow, Jest and Metro to get the module names from the filenames (`Libraries/Animated/src/nodes/AnimatedInterpolation.js` => `AnimatedInterpolation`)
* Checked the Flow configuration by running flow on the project root (no errors):
```
yarn flow
```
* Checked the Jest configuration by running the tests with a clean cache:
```
yarn jest --clearCache && yarn test
```
* Checked the Metro configuration by starting the server with a clean cache and requesting some bundles:
```
yarn run start --reset-cache

Summary:
Looking to address a few new `FlowFixMe`s I had to do some minor refactoring of `MessageQueue`. Has the advantage of (IMO) making things clearer by removing a redundant counter and some gratuitous bitwise operations.
Previously `_callbacks` was an array of `?Function`s where even elements were failure callbacks and odd elements were successes. Each new call incremented `_callID` by one and `_callbackID` by two. I've changed this to use two arrays `_successCallbacks` and `_failureCallbacks` indexed by `callID`. That made the `_callbackID` counter unnecessary and reduced the need for computed indices.
Tested with flow and a quick play with UIExplorer.
