Summary:
Goals are:
1. Catch errors in parsing during dev-mode in a way that is disruptive/grabs attention, but has enough information.
2. Use react_native_assert for hitting breakpoints (less useful for Android, more for iOS), and add LOGs for when this code is used in Android (more useful for Android, less useful for iOS).
3. Return sane defaults so that prod cases don't crash, and don't return totally garbage data.
I also found a couple cases where parsing was incorrect before; see WritingDirection and TextAlignment. This could impact some layouts and RTL/LTR potentially.

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.

Solution: Instead of relying on `RCTModuleData` (which does a ton of things), manually create a `_moduleMethods` array to store the methods that view manager exposes. This manual creation code was copied from how `RCTModuleData` performs lookup.

Summary:
Surprisingly, it's not that trivial to pass `LayoutContrants` to `YGNodeCalculateLayout` in a way that always works. The problem is that `YGNodeCalculateLayout` does not allow expressing the constraints explicitly, so we need to pass them as `YGStyle` properties of a root node. With this approach, we unconditionally apply them as `YGStyle`s as actual values or `Undefined` value (which overrides some other values that can be previously set by calling this function or other code). We also intentionally preserve `height` and `width` values because it's a common use-case when a component explicitly specifies its size.

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:
It is the correct way to deal with the measure function.
I believe it can fix the crash we see with TextInput state update. The crash is probably caused by invalid value of `shadowNodeRawPtr` in `YogaLayoutableShadowNode::yogaNodeCloneCallbackConnector`.
It's hard to reconstruct the full chain of events but I think it's related: Yoga's dirty flag influences cloning, so the improper setting of this flag can misalign "natural" ShadowNode cloning (influenced by changes in the tree) and YGNode-initiated cloning (triggered by layout process).

Summary:
This implements the `MeasurableYogaNode` trait in `YogaLayoutableShadowNode`. We had this trait from the very beginning but never used it. Now, if the trait is specified, `YogaLayoutableShadowNode` will set the measure function for the node and dirty it during cloning.
Previously, we used (and still use) a dedicated method for setting up the measure function - `YogaLayoutableShadowNode::enableMeasurement()`. The problem with it is that to make it work we have to dirty the Yoga node every time we clone it. And the only proper way to do this in the `YogaLayoutableShadowNode` constructor because if we do it later ancestor nodes could not observe this and react to this. Therefore we have to have a trait for it.
The plan is to use it for TextInput first to fix a crash (see the next diff). After we confirm it works fine, we will replace all the usages of `enableMeasurement` with the new trait.
This diff also renames the other two yoga-related traits (to make them less verbose and look unified), adds more comments, and asserts.

Making "layout" event asynchronous unbatched will bring the behaviour closer to Paper.
Paper puts "layout" event in the event queue from ShadowQueue and schedules a flush of event queue on JavaScript queue.
Before this, Fabric puts "layout" event in the event queue from JavaScript queue, waits until main run loop is about to go to sleep and then schedules a flush of event queue on JavaScript thread.
Now Fabric no longer waits for main run loop to go to sleep but induces a flush of event queue on JavaScript thread right away.

Summary:
This changes the way we throttle `onLayout` events in Fabric.
The approach we used before has several issues:
* Every event-dispatching action initiated a lambda scheduled on JavaScript thread (which is a bit inefficient).
* If an event had {0,0,0,0} frame, it might be skipped because this is the default frame value.
* An event was always delivered by the exact block scheduled at the moment of the event initiation (even though some other blocks might be called before). In case of events being initiated rapidly, it can delay actual event delivery and maybe even overwhelm the JavaScript thread.
The new implementation uses a different approach: we maintain the shared storage with recent frame value and use the very first opportunity to deliver it. Alse see comments in the code.

Summary:
In Android, only changed prop values are sent to the mounting layer via folly::dynamic maps. In the LayoutAnimation system, before this, we only sent that
map at the /end/ of the animation for any non-interpolated values (for example, image source is not interpolated so it was not updated until the end of the animation).
However, what we probably expect is that all non-interpolated values change immediately, and interpolated values smoothly transition. This diff makes that change on Android
by using the final RawProps as the /initial/ value that interpolations are stacked on.
