Summary:
## Rationale
The CatalystInstance is going away after we delete the bridge. So, we should migrate away from onCatalystInstanceDestroy() to something else: invalidate().
## Changes
- Introduce the NativeModule.invalidate() cleanup hook.
- Both the NativeModule and TurboModule infra now call this invalidate() method, **as opposed to** onCatalystInstanceDestroy(), to perform NativeModule cleanup.
- **Is this safe?** All our NativeModules extend BaseJavaModule. BaseJavaModule.invalidate() delegates to NativeModule.onCatalystInstanceDestroy(), so NativeModules that implement onCatalystInstanceDestroy(), but not invalidate(), still have their onCatalystInstanceDestroy() method called.

Summary:
The purpose of this change is to make TTRC markers work similarly for bridge loading and bridgeless loading so we could compare performance between them.
There are mainly four cases involved:
```REACT_BRIDGE_LOADING_START,
REACT_BRIDGE_LOADING_END,
REACT_BRIDGELESS_LOADING_START,
REACT_BRIDGELESS_LOADING_END
```
First 2 are for beginning/ending of bridge loading which includes creating fragment, loading JS bundle, running JS bundle and creating react instance. Last 2 are for similar purpose with bridgeless.

Summary:
## Problem:
NativeModules can only be initialized after we mark them initializable on the NativeModules thread. This work is scheduled in ReactInstanceManager.setupReactContext(), after we schedule the execution of the JS bundle on the JavaScript thread in ReactInstanceManager.createReactContext():
https://www.internalfb.com/intern/diffusion/FBS/browse/master/xplat/js/react-native-github/ReactAndroid/src/main/java/com/facebook/react/ReactInstanceManager.java?commit=9b58f58b8eb12281567b8d24d6d000e868e61a1f&lines=1256-1257%2C1331%2C1334-1335%2C1333-1334
So, if the timings don't work out, the JavaScript thread could start executing the JS bundle before the NativeModule thread makes all NativeModules initializable. In this case, those NativeModule will just appear to be null in C++/JavaScript.
## Fix
This diff makes all NativeModules initializable immediately after their ModuleHolder is created. ModuleHolder.markInitializable() simply initializes initializes modules that were eagerly created.

Summary:
This refactors MountingManager into a minimal API that shims into a more fully-featured SurfaceMountingManager. The SurfaceMountingManager keeps track of surface start/stop, surface ID, and surface Context.
This solves a number of issues around (1) race conditions around StopSurface/StartSurface, (2) memory management of Views, (3)
Concrete improvements:
1. Simpler to reason about race conditions around StopSurface/StartSurface.
2. 1:1 relationship between SurfaceId and all Views/tags.
3. When surface is stopped, all descendent Views can be GC'd immediately.
4. Fixed separation of concerns and leaky abstractions: surfaceId/rootTag and Surface Context are now stored and manipulated *only* in SurfaceMountingManager.
5. Simpler StopSurface flow: we simply remove references to all Views, and the Fragment (outside of the scope of this code) removes the RootView. This will trigger GC and we do ~0 work. Previously, we ran a REMOVE and DELETE instruction and kept track of each View in a HashMap. Now we can simply delete the map and move on.
The caveat: NativeAnimated (or other native modules that go through UIManager). APIs like `updateProps` currently uses only the ReactTag and does not store SurfaceId. This is a good argument for moving away from ReactTag, at least in its current incarnation, but: for now this requires that you do a lookup of a ReactTag across N surfaces (worst-case) to determine which Surface a ReactTag is in.
So, to summarize, the "con" of this approach is that now `getSurfaceManagerForViewEnforced` could be slower. It is used in:
* NativeAnimatedModule calls `updateProps` through UIManager
* FabricEventEmitter calls `receiveEvent` on FabricUIManager directly
* On audit, I could find zero native callsites to `sendAccessibilityEvent` through UIManager

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:
When a native module registers itself as a lifecycle event listener, ReactContext will immediately call `onHostResume` if the activity is already in a resumed state. We rely on this behavior for things like NativeAnimatedModule, which only enqueues the frame callback in onHostResume. However, ReactContext only does this if `hasActiveCatalystInstance()` returns true - which makes sense, because we don't want to notify listeners if the instance has been destroyed. But in bridgeless mode, `hasActiveCatalystInstance` returns false, and we never call `onHostResume` in this case.
This diff fixes an issue where native driver animations don't work the first time you navigate to a screen with bridgeless mode enabled.

Summary:
In the past, in Fabric (Android), we never called stopSurface. Ever! This is bad for memory and can cause other issues, so... let's not do that.
Instead, when the ReactRootView is being torn down, we check the View ID to see if it's a Fabric RootView, and if it is, we call Fabric's stopSurface method.
Fabric stopSurface only has impact on (1) Fabric mount instructions being executed after that point and (2) tells JS to stop running the surface, on the JS thread, asynchronously.
Anecdotally it looks like all the MountItems involved in deleting and removing views from the hierarchy are executed before stopSurface is called.
