Summary:
This diff refactors the createViewInstance method in order to ensure that viewID is set before props are updated in the view.
This is necessary because there are components that deliver events at the same time their props are set. This means that some components might not have their viewId set correctly when events are delivered.
Since viewId is used to determine if a view belongs to Fabric or Paper, there are cases when the events are not delivered to the right renderer

Summary:
Right now we assume in the Image component that any prop changes requires a redraw of the image, even if the props set are identical.
Noop prop updates can be caused in Fabric by LayoutAnimations. This may go away in the future, but only when we have a new animations system.
I don't think most other components need to be concerned with this, and many other components already guard against unnecessary redraws. Since the image "flashes"
when it is loaded, unlike most other native components, this issue is more noticeable for images.

## Description
Suppose this was the codegen declaration before:
```
rn_library(
name = "FooModule",
native_module_spec_name = "FBReactNativeSpec",
codegen_modules = True,
# ...
)
```
Previously, this would generate the following BUCK targets:
- generated_objcpp_modules-FooModuleApple
- generated_java_modules-FooModuleAndroid
- generated_java_modules-FooModule-jniAndroid
## Changes
We will now generate:
- FBReactNativeSpecApple
- FBReactNativeSpecAndroid
- FBReactNativeSpec-jniAndroid
This matches the naming scheme of the old codegen.

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.

Summary:
## Context
The legacy NativeModule infra implements promise methods using [async NativeModule method calls](https://fburl.com/diffusion/tpkff6vg). In the TurboModule infra, promise methods [treat as sync methods](https://fburl.com/diffusion/yde7xw71), and executed directly on the JavaScript thread. This experiment makes TurboModule promise methods async, and dispatches them to the NativeModules thread, when they're executed from JavaScript.

Summary:
## Context
Every time we require a NativeModule in Java, we [first try to create it with the TurboModuleManager](https://fburl.com/diffusion/3nkjwea2). In the TurboModule infra, when a NativeModule is requested, [we first create it](https://fburl.com/diffusion/d2c6iout), then [if it's not a TurboModule, we discard the newly created object](https://fburl.com/diffusion/44gjlo6y). This is extremely wasteful, especially when a NativeModule is requested frequently and periodically, like UIManagerModule.
Therefore, in D24811838 (https://github.com/facebook/react-native/commit/803a26cb003e6b790e3a1ab31beb0c95795fff0c) fkgozali launched a fix to the infra that would avoid creating the non-TurboModule object in the first place. Today, we're launching this optimization.

Summary:
Some of the existing files under uimanager/ are self contained and used by the component codegen output. This commit split out those files into a dedicated uimanager/interfaces/ dir/target so that more targets can depend on it without causing dep cycle.
Also, the component codegen output doesn't need LayoutShadowNode at all, so this removed the import.
This will allow us to combine the Java codegen output for TM spec and Fabric components, simplifying build and dependency management (not in this commit yet).

Summary:
There is an optimization in FabricUIManager.surfaceActiveForExecution that ensures it returns the same value (true or false)
for a given SurfaceId for a single frame (the value is cached until the next frame).
It seems like this can be causing a few different crashes, in a couple different ways:
1) If StopSurface is called off the UI thread, in the middle of a batch of operations (probably less likely to cause problems)
2) If StopSurface is called on the UI thread, in between different operations; the latter operations will still execute because the `true` value of `surfaceActiveForExecution` was cached.
I don't think that this optimization was providing much for us, and could be causing crashes. Remove it for now and we'll analyze impact on crashes and perf.

Summary:
The `BlobCollector` native module stored a `jni::global_ref` as a member,
and its destructor automatically destroys it.
However, as noted in JSI documentation, there is no guarantee that the destructor
is run on a JVM-registered thread. The destructor knew this and used a `jni::ThreadScope`
to do some other JNI behavior, but the global_ref needs to be destroyed during
that ThreadScope as well.

Summary:
Props are transferred from C++ to Java using ReadableNativeMaps. The current implementation of ReadableNativeMaps creates an internal HashMap the first time one of its methods is executed.
During the update of props ReadableNativeMaps are consumed only once and they are accessed through an Iterator. That's why there is no reason to create the internal HashMap, which is inefficient from performance and memory point of view.
This diff creates an experiment that avoids the creation of the internal HashMap during prop updates, additionally it removes a lock that was being used in the creation of the internal HashMap. I expect this change to have a positive impact in TTRC and memory (in particular for ME devices)
This diff reduces the amount of ReadableNativeMaps's internal HashMaps created during initial render of MP Home by ~35%.

Summary:
The root cause of this bug is a race condition between the onMeasure method and setupReactContext.
ReactInstanceManager.attachRootView() method is responsible of the initialization of ReactRootViews and it is invoked by ReactRootView.onMeasure() method in the UIThread
Important initialization steps:
1. Clear the Id of the ReactRootView
2. Add the ReactRootView to the mAttachedReactRoots
3. Call StartSurface (if the bridge has been initialized)
Sometimes, when this method is invoked for the first time, the bridge is not initialized, in those cases we delay the start of the surface.
Once the bridge is initialized, StartSurface is called by the setupReactContext() running in the NativeModuleThread.
Since onMeasure can be called multiple times, it is possible that we call "StartSurface" twice for the same ReactRootView, causing the bug reported on T78832286.
This diff adds an extra check to prevent calling "StartSurface" twice. The fix is done using an AtomicInteger comparison and it is gated by the flag "enableStartSurfaceRaceConditionFix". Once we verify this works fine in production we will clean up the code, remove the flags and maybe revisit the API of ReactRoot.
