Summary:
The standard says that zIndex should only be defined for non-`static` positioned views. This diff implements it.
For now, it actually enables zIndex for all views in RN because there is no way to specify `position: static` but will will give that ability by changing Flow definitions in future diffs in a couple of weeks (to ensure OTA safety).

Summary:
In W3C standard, `zIndex` prop can have `auto` value which is the default.
In classic React Native and in Fabric before this diff, the default value was `0`. The only difference between `auto` and `0` is that nodes with `auto` do not form stacking context whereas nodes with `0` (or any other numeric value) do. This worked fine in pre-Fabric RN where every view always formed staking context but in Fabric we need to finally implement it right.

Summary:
In the current Fabric model, we compute layout during the commit phase on the caller thread synchronously. Even though, in general, it's by design the correct way to do it, there are cases where it's *not* a requirement. In such cases, it's more optimal to yield early and continue execution of the commit process on a different thread asynchronously.
One of such cases potentially is `completeRoot` call. There we don't need to return anything and can resume JavaScript execution immediately.
The performance implications of that are not clear but there is a hope that it can free up to ~100ms of JavaScript execution time which is currently spent waiting for layout calculation (and other aspects of the commit phase).
This is an implementation in the core. The plan is to test that on iOS first and then, in case if the results of the experiment are positive, to implement it on Android as well.

Summary:
Unfortunately LayoutAnimations index adjustment is a bit tricky. There was one (hopefully only one!) remaining issue where a specific series of delayed removes, inserts, and removes would trip up index adjustment. Namely in this case: Preexisting delayed removes, and then a later animated commit with immediate inserts followed by higher-index removes.
This case is now resolved and I took time to test and verify other index adjustment paths.

Summary:
Now Yoga.cpp does not use the `YGPositionTypeRelative` value/constant, it uses `YGPositionTypeAbsolute` instead.
Now `YGPositionType` can only be `YGPositionTypeRelative` or `YGPositionTypeAbsolute`, so expressions `x == YGPositionTypeRelative` and `x != YGPositionTypeAbsolute` are equivalent.
The reasoning behind the change is that in all cases we actually check a node to be (or not to be) `absolute`, not `relative`. This will make a difference in the coming diffs in the stack when we will introduce a new value for the type: `static`.
We need to differentiate `static` and `relative` values t implement the `stacking context` feature in the W3C-compliant way (to fix bugs and avoid developer confusion). Read more here:

When calling "measure" on ScrollView's children, origin needs to be adjusted for ScrollView's content offset.
For this scrollView uses `getTransform` to adjust frames of its children.
This is wrong because transform is applied to ScrollView as well.
Example:
ScrollView is scrolled 900 points and its origin is {0, 0}, if you call "measure" on the ScrollView, our current measure infra will report its origin being {0, 900}.

Summary:
## Context
1. In FBReactModule jsExecutorForBridge, we asynchronously initialize a list of TurboModules on the main queue: https://fburl.com/diffusion/i56wi3px
2. After initializing the bridge, we start executing the JS bundle, here: https://github.com/facebook/react-native/blob/e23e9328aa164d0a70fe4f16042c982e7801d924/React/CxxBridge/RCTCxxBridge.mm#L414-L417. Since bridge initialization knows nothing about TurboModule eager initialization, this happens concurrently with 1, and starts requiring NativeModules/TurboModules on the JS thread.
## The Race
1. Both the main thread and the JS thread race to create a TurboModule that requires main queue setup.
2. The JS thread wins, and starts creating the TurboModule. Meanwhile, the main thread blocks, waiting on a signal here, in RCTTurboModuleManager: https://github.com/facebook/react-native/blob/e23e9328aa164d0a70fe4f16042c982e7801d924/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm#L430
3. The JS thread tries to dispatch_sync to the main queue to setup the TurboModule because the TurboModule requires main queue setup, here: https://github.com/facebook/react-native/blob/e23e9328aa164d0a70fe4f16042c982e7801d924/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm#L402
4. We deadlock.
## The fix
Succinctly, NativeModule eager initialization finishes before execute the JS bundle, but TurboModule initialization doesn't. This diff corrects that mistake.
The changes in this diff:
1. The RN application via the TurboModuleManager delegate can now optionally provide the names of all eagerly initialized TurboModules by implementing two methods `getEagerInitModuleNames`, `getEagerInitMainQueueModuleNames`.
2. The TurboModuleManager grabs these two lists from the delegate, and exposes them to its owner via the `RCTTurboModuleRegistry` protocol.
3. The RCTCxxBridge, which already owns a `id<RCTTurboModuleRegistry>` object, uses it to eagerly initialize the TurboModules in these two lists with the correct timing requirements.
This is exactly how we implement eager initialization in Android.
**Note:** Right now, phase one and two of TurboModule eager initialization happen after phase one and two of NativeModule eager initialization. We could make the timing even more correct by initializing the TurboModules at the exact same time we initialize the NativeModules. However, that would require a bit more surgery on the bridge, and the bridge delegate. I think this is good enough for now.

Summary:
Changelog: [Internal]
FindNoteAtPoint takes transformations into account. There is however a problem with how transformation in ScrollView. In ScrollViewShadowNode, getTransform is overriden. In the override we apply `Transform::Translate(-contentOffset.x, -contentOffset.y, 0)`, this means that ScrollView has moved by {-x,-y}. However this is only true for its children, not for scroll view itself. This trips off findNodeAtPoint and if you scroll more than than screen's height, point will not be evaluated as inside ScrollView.
Until we can figure out how to deal with this properly, I think it is better to disable it as usage of JS Inspector is more common in ScrollViews than it is with transformed views.

Summary:
After years of trying to design a somehow decomposed and universal layout API, I think we chased a wrong goal. None of the solutions that I tried helped with simplicity, composability, performance, or readability. Besides that, a bunch of execution primitives we use (e.g. `setHasNewLayout`) are heavily influenced by Yoga and are far from being commonly applicable. Finally, we ended up with a situation where the current design does not allow us to implement the features we want (more about that in coming diffs).
The diff changes that. Now we have only one method that implements layout - `layout()`; all possible implementations are free to implement it in any way that makes sense for a particular approach. And, I think, even for the base case - Yoga powered layout - things are much simpler and faster now: it's easy to comprehend how a single method works and now we don't have two loops and an expensive call to `getLayoutableChildNodes`.
But most importantly, after this change will be able to implement the `Inset Overflow` feature quite easily.
