Summary:
This diff finally uses all facilities from the previous diffs to build an implementation of `RCTMountingTransactionObserving` protocol which does *not* require using expensive Objective-C runtime features.
In the coming diffs, we will see how it can/should be used.

Summary:
See the comment in RCTMountingTransactionObserving first.
I think we have to add this to the iOS mounting layer to be able reasonably easy implement things like:
* MovableNavigationBar: seems, currently we don't handle the situation when the container was mounted first and the nested scroll view second.
* TTI component: It does not have access to telemetry.
The protocol is meant to replace `RCTSurfacePresenterObserver`.

Summary:
This diff introduces RCTComponentViewDescriptor - the container for a view and associated with this view properties which mounting infra uses for bookkeeping (and recycling) views.
The previous implementation used raw Objective-C pointers to `UIView`s to store and manipulate them. The new way has a bunch of advantages:
* It allows using high-performant C++ data collections for storing views and their properties (in future diffs).
* The new approach allows us to avoid hacks around NSMapTable (such as ` [_registry setObject:componentView forKey:(__bridge id)(void *)tag];`) that were needed because NSMapTable wasn't designed for our use-case.
* Dealing with `RCTComponentViewDescriptor` which stores a pointer to a view sometimes is actually more efficient than dealing with those pointers themselfs because we can deal with `const &` to a descriptor which does not require a ref-counter bump.
* A new approach is much more flexible, it allows us to store additional data alongside view instances which we will use in coming diffs.

Summary:
In addition to already exiting method `componentViewByTag`, this diff adds a new one `findComponentViewWithTag` which does pretty much the same thing but returns `nil` in a case when it cannot find a view with a given tag. The first method now returns a non-nullable object, whereas the second (new) one return nullable.
We need this to explicitly designate call-sites that are resilient to such kind of errors, where such errors are expected because of still-existing consistency problems (because of some legacy implementation approaches).
At the same time, for the call-sites where a missing view situation is unrecoverable, we should throw early and stop paying for nullability overhead.
In the future diffs, we will change the internal implementation of the registry where the price for dealing with nullability will be actually meaningful.
This is the first diff on the road to an implementation of `RCTMountingTransactionObserving` protocol.

- `tvParallaxShiftDistanceX`
- `tvParallaxShiftDistanceY`

Summary:
I've been working on a new iOS experience with lots of text inputs and this has been driving me a bit nuts…
If you're in a scrollview with `keyboardShouldPersistTaps="handled"` and you tab through your text-inputs, you aren't able to tap outside of a given text-input to blur it (and dismiss the keyboard).
I wrote up a quick explanation and some repo steps here: https://snack.expo.io/BJBcKgrqB
The patch i came up with, after poking around for a little bit seems terrifying - so almost certainly not it. But if it's helpful at all - decided to just got ahead and submit it.

Summary:
This diff changes how arbitrary-node-replacing (aka `RootShadowNode::clone`) algorithm works.
Original implementation worked this way: We specified a node that needs to be replaced and a new replacement node. Then the algorithm finds a node with *the same family* as given the to-be-replaced node and replaced that with a given replacement.
The problem with this approach is that we are replacing a node that we have very little info about (we only know that it shares the same family as specified one). At the same time, we build the replacement based on the exact node that we have. Then imagine the case in which the "target" node can progress/change between a moment where we get a reference to it and a moment where we are trying to clone the tree. In this case, we will replace a "progressed" node with a modified version of the obsolete node.
Practically speaking, it was possible that during a state update we were replacing a node that just got new children with a bit older version of that with old children but with a new state.
How to deal with it? This diff introduces a new interface for this method that allows separating the target node and the actual act of cloning the corresponding node. Instead of specifying actual replacement, we now specify a function that performs the cloning/transformation on-demand on the very exact node that was in the tree at the moment of cloning.
This change does not change/affect any ownership-related relationships between trees and/or nodes.
Ideally, probably, the interface should accept ShadowNodeFamily instance instead of a ShadowNode instance to make the behavior very clear but that requires a bunch of low-level changes that it out of the scope of this fix.

Summary:
Testing the waters with an idea for unifying RN lifecycle with/without bridge.
### Motivation/Background
RN bridge is being reloaded from [several different places](https://fburl.com/codesearch/ae3zeatt). When this happens, the bridge does a bunch of things:
1. Post `RCTBridgeWillReloadNotification` (RCTSurfacePresenter listens to this and reloads)
2. Invalidate batched bridge, which does:
a. invalidate display link
b. post `RCTBridgeWillInvalidateModules/RCTBridgeDidInvalidateModules` (TurboModuleManager listens to this and reloads modules)
c. clear js thread state
d. clear some local caches
3. Set up (reload bundle and batched bridge)
In a bridgeless world, there isn't one thing which owns all these peices of infra, and can reload them.
### Plan
Use `RCTReloadCommand` to handle reloads. This light class previously only handled CMD+R. The new workflow looks like this:
1. Anything which cares about reloads can register itself as a listener. (RCTBridge, RCTSurfacePresenter, TurboModuleManager...)
2. Anything that previously called `bridge reload` now calls `RCTTriggerReloadCommandListeners`.
3. Delete old notifications
### Alternate Plan
Use yet another NSNotification. I like `RCTReloadCommand` better.
### Unknowns
Looks like we log the reason for bridge reloading [here](https://fburl.com/diffusion/lc9jj8la), do we want to save this behaviour? Does anyone look at why bridge is being reloaded cc/Rick? If so, I can add back that functionality to `RCTReloadCommand`.
It should be possible to customize the order/priority of what gets reloaded first. There may be some racy behaviour that I haven't thought about yet.

Summary:
See T55861104. In rare cases if `removeReactInstanceEventListener` is called right after (like, a small number of CPU instructions later, on a different thread) we allocate the `listeners` array with a certain size, then we could have one or more `null` listeners in the array, which is what we've been seeing in prod, at very low volumes, for several years. Without solving the root of the race condition we can just add a null check here.
Maybe it's also possible that if `addReactInstanceEventListener` is called on another thread in a racey way, that the size will be incremented on the array before we can access the additional member. That seems crazy, but maybe.
While this has been firing for multiple years it seems like a more recent change caused a regression. This diff doesn't address that and only resolves the crash.
