Summary:
LLD, our new iOS linker, is an ongoing effort to migrate our old outdated ld64 linker. As part of our effort to rollout LLD to all apps, we are making sure LLD reaches parity with ld64.
Due to Identical Code Folding (ICF), LLD and ld64 handles strings differently. LLD treats each string as a separate object in memory even if the values of the strings are the same. ld64 happens to aggregate these values across files. This behavior creates a subtle difference on our codebase when we start comparing by value or by reference.
`char * ` fields from `RawPropsKey.h` are using `==` which compares by its address. Here, we cast the buffer to a string to make the comparison, while avoiding the cast if one happens to be null.

Summary:
Fabric core uses a lot of traits - I am reserving a few more for core usage, and also exposing a few "unreserved" traits.
It is recommended that all custom components that do use traits rely on these constants instead of hard-coding any trait values. That way, in the unlikely event that these values change in the future, it will not break components.

Summary:
Adding runtime type information adds greatly to the binary size, so react-native-windows builds without it. But some parts of the fabric code currently uses dynamic_cast, which means to use fabric we have to build with RTTI turned on. This PR removes the usages of dynamic_cast that are hit in release builds, which should allow react-native-windows to turn off RTTI in release builds.
Required for: https://github.com/microsoft/react-native-windows/issues/7981
One thing to note, the comment in ShadowNodeTraits indicates that core was reserving the first 16 bits. I'm adding two more. Is that ok? Should core be reserving more for future use?

There is a possibility of race between updating scrollview's state and virtualised list asking for layout of individual cells.
To make sure the race doesn't happen, state must be updated before dispatching onScroll event.
Android has implemented a different mechanism to tackle this issue in D28558380 (https://github.com/facebook/react-native/commit/b161241db2ef74d2e4bff36d4972f5f0312dcc44).

This is a mechanism that will guess event's React priority based on other events ongoing on the platform.
If an event happens within span of ContinuousStart -> ContinuousEnd and its category is unspecified, we deduce it's React priority to be default. All other events are discrete.
Special case: `onScroll`, which is always treated as "Default".

Summary:
TL;DR: simplify and delete a bunch of stuff that shouldn't be necessary in Fabric.
I discovered that this event dispatcher (and the older one this is based on) is triple-queueing: we queue events into "staging", and then post "dispatch events" to only run /on the JS thread/. Even in Fabric. Then, each of these events is emitted into C++ where they are queued /again/! This refactor eliminates one more level of queueing - instead of scheduling dispatch for the JS thread, we just emit them directly to C++ when they're received in Java.
Unfortunately, the EventDispatcher is also used to drive AsyncEventBeat in C++:
1. EventBeatManager.onBatchEventDispatched: https://fburl.com/diffusion/qf6dyhsw
In the C++ impl, it indirectly will drive the AsyncEventBeat/AsyncEventBeatV2.
2. onBatchEventDispatched is ONLY called from EventDispatcherImpl: https://fburl.com/codesearch/mxk8ifyj
3. Which is queued and only runs on the JS thread: https://fburl.com/codesearch/czvbst4u
This means the AsyncEventBeat is only ticked when the JS thread is free, and ticks will be skipped when the JS thread is occupied for long periods.
Now, in this refactor, when this class is used it will drive AsyncEventBeat on every UI tick. This is also potentially not correct. On iOS (Fabric), AsyncEventBeat is driven when the UI thread is "about to sleep".
For now I'm not going to worry about that detail - it is significant, but Fabric+Android is currently /not doing the right thing/ and it's not clear that we want to maintain iOS behavior. This is something we need to discuss further and figure out.

Summary:
Changelog: [internal]
My suggestion is to simplify event dispatching to only two options, synchronous and asynchronous.
Why?
- Fabric has only been using one queue, `AsynchronousBatched`.
- Batching happens even on `AsynchronousUnbatched`. It just batches events until JS thread starts processing them instead of waiting for the main run loop.
- It will make it easier to reason about the code in the future once we start utilising different priorities for Concurrent Mode.

### Why does the crash happen?
The crash can happen if runtime is destroyed before background executor lambda is run. Destroying a shadow node after runtime leads to a crash through the chain of ownerships.
Chain of ownership:
`ShadowNode -> ShadowNodeFamily -> EventEmitter -> EventTarget -> Pointer`
Pointer tries to call `invalidate` method on raw pointer to the runtime which is gone.
https://www.internalfb.com/intern/diffusion/FBS/browse/master/xplat/js/react-native-github/ReactCommon/jsi/jsi/jsi.h?commit=2ee3ae0c6a64&lines=335-339
To work around this, weak pointers are passed to lambda. This way the lambda is less likely to be the last owner of shadow nodes. Possibility of race still exists but it less likely to happen.
## Other solution
Alternatively, we could make sure native Runnable queue in Java is emptied as part of tear down process. We can even implement both solutions as they are semantically correct.
