Summary:
Unfortunately, parsing some props requires stateful context - namely, PlatformColor on Android. We explored several different options but they all seemed inferior to the approach of using ContextContainer, and most would require using global state.
By introducing this change everywhere as early as possible, we can avoid later pain. It is likely that some prop, on some platform, will require this mechanism. We'll be ready for it!
Because we can pass a constref of the ContextContainer through to all props and because the context and context data is never retained by prop parsers, perf and memory hit should be ~0.
This diff contains core changes only. Leaf changes to all props structs and conversions files will be in next diff(s).

Summary:
PreAllocation currently always happens at revision 0 (after ShadowNode creation), and all CREATE mutations are triggered for ShadowNodes at revision 1 or higher (since CREATE mutations are generated by the differ, it means that all ShadowNodes have revision 1 or higher when CompleteRoot is called). This means that between PreAllocation and CREATE, we /always/ expect at least one clone.
It is possible for a node to be "non-view-forming" at revision 0, causing view preallocation to be skipped, and "view-forming" at revision 1 (causing the CREATE mutation to be thrown away, since all CREATE mutations of revision 0 or 1 are thrown away). This causes a crash. It is extremely marginal, but there are repros in the wild.
Thus, I'm introducing one new UIManager and Scheduler delegate method that allows the mounting layer to be notified of clones. If a clone from rev 0->1 results in a node going from non-view-forming to view-forming, we can preallocate then, as well.
This resolves this crash, and allows us to keep experimenting safely with this View PreAllocation optimization. I believe all edge-cases are accounted for.

Summary:
This diff adds a new variable called "DisplayMode" into SurfaceHandler.cpp and FacebookAppRouteHandler.js. The purpose of DisplayMode is for the native pre-render system to notify React that the a surface is either being "pre-rendered" or "rendered"
When the surface is being "pre-rendered" (displayMode == "SUSPENDED"), react will create and commit React Trees, but it will not execute use-effect callbacks
When the surface is being "rendered" (displayMode == "VISIBLE"), react will create and commit React Trees and it will not execute all use-effect callbacks that weren't executed during "pre-rendering"
By default surfaces are going to be rendered with displayMode == "VISIBLE".
This diff should not create any change of behavior for now, this is the infra required to integrate the new offScreen API the react team is working on for pre-rendering system

Introducing LeakChecker. A tool that checks if all native components have been cleaned up when surface is stopped.
**Known shortcomings**:
- LeakChecker is only enabled in debug builds and the existence of leaks is logged to console.
- For now, Leak Checker looks at N-1 screen. This is intentional as there is a known limitation of React that doesn't free up all shadow nodes when surface is stopped. Because of this, the use of LeakChecker is not intuitive and I'll work with React team to try to work around this.
- It doesn't help locating the leak, it only informs that leak is present. I'll be looking into ways to help locate the leak.

Right now there are places in UIManagerBinding.cpp where native java exceptions will be thrown if calling JSI functions results in errors, such as:
```Trying to report error getPropertyAsObject: property '__fbBatchedBridge' is undefined, expected an Object
Error: getPropertyAsObject: property '__fbBatchedBridge' is undefined, expected an Object
```
https://www.internalfb.com/intern/logview/details/facebook_android_javascripterrors/358181062b47b9561e60427bbb3816a9
In this diff I added LOG(ERROR) and checks because:
1, Throwing errors neither prevents the JSI errors nor handles them properly, checks prevent JSI errors from happening.
2, Errors are aggregated in Logview with other JSI errors as "Error: android_crash:com.facebook.react.devsupport.JSException:facebook::jni::throwNewJavaException" which keeps the SLA task open forever, checks can prevent JSI errors so they won't lead to exceptions, and LOG(ERROR) will make sure we have enough info for debugging.

Summary:
Changelog: [internal]
### Why does the crash happen?
The crash can happen if runtime is destroyed before background executor lambda is run. Destroying a shadow node after runtime leads to a crash through the chain of ownerships.
Chain of ownership:
`ShadowNode -> ShadowNodeFamily -> EventEmitter -> EventTarget -> Pointer`
Pointer tries to call `invalidate` method on raw pointer to the runtime which is gone.
https://www.internalfb.com/intern/diffusion/FBS/browse/master/xplat/js/react-native-github/ReactCommon/jsi/jsi/jsi.h?commit=2ee3ae0c6a64&lines=335-339
To work around this, weak pointers are passed to lambda. This way the lambda is less likely to be the last owner of shadow nodes. Possibility of race still exists but it less likely to happen.
## Other solution
Alternatively, we could make sure native Runnable queue in Java is emptied as part of tear down process. We can even implement both solutions as they are semantically correct.

Summary:
Building ReactAndroid from source on Windows has recently hit the limitation of maximum path lengths.
At build time, during the `:ReactAndroid:buildReactNdkLib` task, the linker tries to access several of the intermediate binaries located deep in the tmp folder hierarchy, eg.
```
D:\r\ReactAndroid\build\tmp\buildReactNdkLib/local/armeabi-v7a/objs/react_render_components_progressbar/D_/r/ReactAndroid/__/ReactCommon/react/renderer/components/progressbar/android/react/renderer/components/progressbar/AndroidProgressBarMeasurementsManager.o
```
**Suggested fix:** for modules such as `react_render_components_progressbar` and `react_render_components_picker`, rename them to `rrc_progressbar` etc.
**NOTE**: this assumes that the fix from https://github.com/facebook/react-native/issues/30535 is in place. This regression happened while https://github.com/facebook/react-native/issues/30535 has been pending checkin.
**Other mitigations I've tried:**
- setting [`LOCAL_SHORT_COMMANDS`](https://developer.android.com/ndk/guides/android_mk#local_short_commands) for the problematic modules or `APP_SHORT_COMMANDS` for the root project. Turns out those commands don't work on the NDK version RN requires, but even after manually applying a [patch ](https://android-review.googlesource.com/c/platform/ndk/+/1126440) to my local copy of the NDK, these flags had no effect.
- moving the repo directory higher in the file system tree, and using short directory names `D:\r\...` was not enough
- creating virtual drive letters for specific long paths with the [`sust`](https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/subst#examples) command is not workable, since they depend on the source folder structure, and get partly generated by the build system, which I can't plug into
- just enabling long path support on Windows is not enough, since the compiler toolchain doesn't support them.

Summary:
This replaces the internal core implementation of `setState` with the new `updateStateWithAutorepeat` which is now the only option.
In short, `updateStateWithAutorepeat` works as `setState` with the following features:
* The state update might be performed several times until it succeeds.
* The callback is being called on every retry with actual previous data provided (can be different on every call).
* In case of a static value is provided (simple case, not lambda, the only case on Android for now), the same *new*/provided value will be used for all state updates. In this case, the state update cannot fail.
* If a callback is provided, the update operation can be canceled via returning `nullptr` from the callback.
This diff removes all mentions of the previous state update approach from the core; some other leftovers will be removed separatly.
