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:
When maxLength is defined in <TextInput>, if the last character at max length is an emoji, the content of the input is cleared:
{F620865178} {F620865237}
Related Github issues:
https://github.com/facebook/react-native/issues/10929https://github.com/facebook/react-native/issues/10964
## Root cause:
When NSString was created, unicode characters were 16-bit long, so Objective-C considers every unicode character as 16-bit. However, unicode was later extended to more than 16bit, for example, emojis, which causes NSString substring method cuts off at the wrong position.
Example:
```
NSString *s = @"abc{emoji:1f601}";
NSInteger len = s.length; //length is 5 (as {emoji:1f601} occupies two 16-bit characters)
NSString *s3 = [s substringToIndex: 3]; //s3 is "abc"
NSString *s4 = [s substringToIndex: 4]; //s4 is null!
```
If string s, "abc{emoji:1f601}", is entered in <TextInput>, which has max length 4, it will truncate the string to the first 4 characters, "cutting" the emoji in half which causes encoding error and returns null. The text input is cleared.
## Solution:
If the character at max length is longer than 16-bit, truncate the character BEFORE it instead. In the previous example, truncate till index 3 instead of 4. The end result will be "abc" and the emoji is dropped.
## Changelog:
[iOS] [Fixed] - <TextInput> content is reset when emoji is entered at the max length

Summary:
Problem: In paper, there is a handy API called `[uiManager viewForReactTag:]`. Fabric does not have this mapping. The Fabric interop layer still relies on this Paper mapping.
Solution: As a workaround, re-create this mapping in the Fabric interop layer. Therefore, whenever Fabric interop layer asks a paper view manager to create a view, store a weak reference to the view in a `NSMapTable`. NSMapTable allows us to customize the strong/weak relationship. I've added a comment explaining that `RCTWeakViewHolder` only needs to be used for this special circumstance.

- 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.

Summary:
We need to register a root view component here synchronously because right after we start a surface, it can initiate an update that can query the root component.
This fixes an issue in Fabric Surface caused by a data race between registration of root component and concurrent call to `constraintLayout` on the main thread.
This how it happens:
1. We call `startSurface` on some background thread;
2. As a result `[RCTFabricSurface start]` schedules a lambda to the main thread that will register a root component.
3. Meanwhile some other code on the main thread changes the layout and requests the relayout of a surface.
4. Because the surface is already running, the `constraintLayout` method works as expected and schedules a mutation instruction that changes the size of the root component.
5. The mutation instruction is being delivered synchronously on the main thread and fails because the root component was not yet registered. Boom.
For now, it's not fully clear how to solve this problem properly. I suspect that the good solution would be to shift the responsibility of registering a root component to the MountingCoordinator side (so, we will have an explicit instruction prescribing creating and registering the root component). This will probably be a quite invasive change though.
For now, I think it's fine to make the block synchronous to avoid the race.

* All the state changes initiated from RCTFabricSurface are performed via calling corresponding methods on SurfaceHandler (bypassing RCTSurfacePresenter, RCTScheduler, Scheduler, and UIManager).
* Every RCTSurfaceHandler is responsible for observing `UIContentSizeCategoryDidChangeNotification` and communicating the change down to SurfaceHandler. (Besides code simplifications it's more correct because on iOS the DPI actually depends on a particular UIScreen/UIWindow associated with UIView and *not* global for the whole app.)
