This PR removes most of the tvOS remnants in the code. Most of the changes are related to the tvOS platform removal from `.podspec` files, tvOS specific conditionals removal (Obj-C + JS) or tvOS CI/testing pipeline related code.
In addition to the changes listed above I have removed the deprecated `Platform.isTVOS` method. I'm not sure how `Platform.isTV` method is correlated with Android TV devices support which is technically not deprecated in the core so I left this method untouched for now.
## Changelog

Summary:
When an animation is completed or a conflicting animation is detected, force props, state, layout, etc to update.
Currently, when a final animation mutation is queued, some attributes can be updated but not others, causing unexpected visual glitches at least on Android.
Some of these are arguably component bugs, but it's easier to just flush all attributes by tricking the platforms into updating all attributes. This will also prevent us from having to track down more of these bugs, potentially.

Summary:
In this diff I simplify index adjustment and add comments to rigorously describe what we're doing at each step of index adjustment.
I've also made unflattening detection more correct, robust, and slightly more efficient.
Bugs that existed before:
1) The reparenting detection that existed in the animations layer had some subtle bugs. I don't have proof that it results in any correctness issues or crashes, but I suspect it.
2) Correctness of index adjustment: there were cases where the Android mounting layer would crash because LayoutAnimations would try to remove a View at an index, but the index was wrong. This is why I sat down and diagrammed the relationships between all the bits of data we have for index readjustment - I believe this to be correct now.
3) Correctness of INSERT index adjustment: I had the insight that when we have batches of INSERTs to consecutive indices, we essentially want them to be treated as a single INSERT for adjustment purposes, so that they're all placed consecutively in the view layer. I added `ConsecutiveAdjustmentMetadata` to deal with this, and there are more comments in the code.

Summary:
Exceptions in C++ work quite differently from exceptions in other languages. To make exceptions actually work **correctly** all the code needs to be written with "exceptions in mind" (e.g., see https://www.stroustrup.com/except.pdf). In short, if the code is not "exceptions ready", throwing an exception causes memory leaks, dangling pointers, and invariant violations all over the place, which will probably cause another crashes down the road (which will be especially hard to investigate and attribute to the original issue).
Fabric Core (Layout, Props parsing, ShadowNodes management, and so on) does not use exceptions because in most (all?) the cases the exception is now recoverable. So, if a program detects some internal state invariant violation or missing some resource, *logically* it's fatal. We also don't want to pay code-size and performance tax for exception support, so that's why we don't use them. It's just not the right fit for Fabric Core.
This does not mean that exceptions don't happen though. C++ standard library can throw them... sometimes. And if our library is compiled with exceptions enabled (still the case, unfortunately), an exception can bubble to JavaScript code and losing all context down the road. And it's hard to investigate such crashes. To isolate those occasional exceptions inside C++ core we are marking all C++/JS boundaries with `noexcept` that stops the bubbling.
I hope that will give us much more informative crash reports.

Summary:
Inside JavaTurboModule, the native `CallInvoker` is used to schedule work on the NativeModules thread. So, in ~JavaTurboModule(), I scheduled some work on the NativeModules thread. This work holds a copy of the JNI global reference to the Java NativeModule object, and when it's executed, it resets this global reference to the Java NativeModule object. This should ensure that the we don't access the JVM in ~JavaTurboModule, which could crash the program.
I also removed the redundant `quitSynchronous()` in `~CatalystInstanceImpl()`, to prevent the NativeModules thread from being deleted before we delete the `jsi::Runtime`. This shouldn't cause an issue, because we delete the NativeModules thread when we call [ReactQueueConfigurationImpl.destroy()](https://fburl.com/codesearch/p7aurwn3).

Summary:
Under Fabric only, we can enter an infinite layout loop where the emitted layout event oscillates between two height values that are off by a very small amount.
The cause is, in part, components that use layoutEvents to determine their dimensions: for example, using onLayout event "height" parameters to determine the height of a child. If the onLayout height changes rapidly, the child's height will change, causing another layout, ad infinitum.
This might seem like an extreme case but there are product use-cases where this is done in non-Fabric and layout stabilizes quickly. In Fabric, currently it may never stabilize.
Part of this is due to a longstanding issue that exists in Fabric and non-Fabric, that we cannot immediately fix: If in a single frame, C++ emits 100 layout events to ReactJS, ReactJS may only process 50 before committing the root. That will trigger more layout events, even though product code has only partially processed the layout events. At the next frame, the next 50 events will be processed which may again change the layout, emitting more events... etc. In most cases the tree will converge and layout values will stabilize, but in extreme cases in Fabric, it might not.
Part of this is because Fabric does not drop *stale* layout events. If 10 layout events are dispatched to the same node, it will process all 10 events in older. Non-Fabric does not have this behavior, so we're changing Fabric to drop stale events when they queue up.

Summary:
This change maps the three most used colors (black, white, clear) to corresponding predefined values in UIColor. This should meaningfully reduce the overall amount of allocated UIColor/CGColor objects. In my non-scientific measures, it reduces the number of CGColor objects from ~1500 to ~1000. And... it no much at least in terms of kilobytes. However, I still think it's a good idea to implement this because I hope that can remove some work from memory allocation infra and maybe enable some optimizations that UIKit hopefully does for black and white colors. (I tend to believe that this optimization exists because UIKit even has a classes called UIDeviceWhiteColor and UICachedDeviceWhiteColor.)

Summary:
Finally, this diff changes the internal implementation of SharedColor to be `optional<int>`.
Initially, when we started working on the new renderer, it seemed like a good idea to allocated CGColor objects ahead of time and store them with Props. Now, this idea does not look so good, especially because:
* Having `SharedColor` as a `shared_ptr` is a quite big perf overhead for copying this thing. And the size of the object is not small.
* Having `SharedColor` as a `shared_ptr` creates huge interconnectedness among pieces of the core and rendering. E.g. improper releasing a pointer in some component view can cause a crash somewhere in the core (because both places might use the same shared `blackColor`.
On Android, we already use simple `int` as a representation of a color, and this works great. And this diff implements something very similar to Android, but a bit differently: here we use `optional<int>` instead of custom class with a single `int` field and some magic value that represents "empty value".
This approach should fix T75836417 because now we don't have allocation and deallocation when we simply assign color values.
If this solution works fine on iOS, I will do unify all implementations among all platforms.

Summary:
Right now nested Text components are not accessible on Android. This is because we only create a native ReactTextView for the parent component; the styling and touch handling for the child component are handled using spans. In order for TalkBack to announce the link, we need to linkify the text using a ClickableSpan.
This diff adds ReactClickableSpan, which TextLayoutManager uses to linkify a span of text when its corresponding React component has `accessibilityRole="link"`. For example:
<Text>
A paragraph with some
<Text accessible={true} accessibilityRole="link" onPress={onPress} onClick={onClick}>links</Text>
surrounded by other text.
</Text>
With this diff, the child Text component will be announced by TalkBack ('links available') and exposed as an option in the context menu. Clicking on the link in the context menu fires the Text component's onClick, which we're explicitly forwarding to onPress in Text.js (for now - ideally this would probably use a separate event, but that would involve wiring it up in the renderer as well).
ReactClickableSpan also applies text color from React if it exists; this is to override the default Android link styling (teal + underline).

Summary:
This fixes TextInput measurement caching. Previously we were not setting the correct Spannable in the cache; we needed to additional Spans to it to indicate font size and other attributes.
This brings Fabric closer to how non-Fabric was measuring Spannables for TextInputs (see ReactTextInputShadowNode.java).
This should fix a few crashes and will be most noticeable with dynamically-sized multiline textinputs where the number of lines changes over time.
This also allows us to transmit less data from C++ to Java in the majority of cases.

Summary:
One of the operations we do in `Scheduler::stopSurface()` is committing an empty tree to free up `ShadowNode` objects and "disable" `EventEmitter`s associated with them. Before this change, we had a gap in time between a moment when we commit an empty tree and remove the tree from the registry. During this time gap, JavaScript (or native, actually) can commit another tree and mount another new state on the screen. To prevent this, we remove the tree from the registry first and only then commit an empty tree to a uniquely owned tree.
Note that the deleted comment says that we actually have to have a tree in the registry for committing an empty tree, I don't think it's true now.
