`UIManagerBinding createAndInstallIfNeeded` happens After `ReactInstance loadScript -> evaluateJavaScript`: install Fabric UIManager before main bundle execution

Summary:
Changelog: [Internal] Remove unused RuntimeExecutor from UIManagerBinding constructor
Since [UIManager is the class that has a reference to RuntimeExecutor](https://github.com/facebook/react-native/blob/ce50c43986bae05ad62552be46f4d5bb4a46f097/ReactCommon/react/renderer/uimanager/UIManager.h#L35-L36), there's no reason for `UIManagerBinding` to own a reference to RuntimeExecutor too.
The purpose of `UIManagerBinding` is to bind the Fabric `std::shared_ptr<UIManager>` in C++ to `global.nativeFabricUIManager` in JS.
Doing this cleanup to make the next diff easier.

Summary:
changelog: [internal]
React on web uses microtasks to schedule a synchronous update for discrete event. Microtasks are not yet available in React Native and as a fallback, React uses native scheduler and task with immediate priority. Until Microtasks are in place, React Native needs to make sure all immediate tasks are executed after it dispatches each event.
I tried to stay as close to [microtask standard](https://developer.mozilla.org/en-US/docs/Web/API/queueMicrotask) as I reasonably could.
Once microtasks on RN are shipped, this code can be removed.

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:
Changelog: [internal]
My suggestion is to simplify event dispatching to only two options, synchronous and asynchronous.
Why?
- Fabric has only been using one queue, `AsynchronousBatched`.
- Batching happens even on `AsynchronousUnbatched`. It just batches events until JS thread starts processing them instead of waiting for the main run loop.
- It will make it easier to reason about the code in the future once we start utilising different priorities for Concurrent Mode.

Summary:
Changelog: [internal]
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.
