Summary:
This diff fixes an issue in `TextInput` where `TextInputState.currentlyFocusedInputRef` could maintain a ref to a view that no longer exists. This issue was exposed when upgrading React, where cleanups for passive effects are deferred. This change means that `inputRef.current` would no longer reference the host view *to be* destroyed; it would be null because the view was *already destroyed*.
There are two fixes here that would independently fix the bug and fix the issue better together.
First, we convert `useEffect` to `useLayoutEffect`. `useLayoutEffect` is intended to fire synchronously after all host view mutations, and the cleanup function is intended to fire synchronously before the host view is destroyed, similar to the behavior assumed before. This change is now the correct function to use semantically. However, if we made this change without the second then any change in the order the effects fire would surface the same bug.
So second, move the `inputRefValue).blur()` call to the same effect as unregistering. This is because we currently require the `blur` effect to be called to null out `currentlyFocusedInputRef` in addition to calling `unregisterInput`. That makes the semantic ordering of effects in `TextInput` meaningful. Instead, when a TextInput is unregistered we should always `blur` to clear the `currentlyFocusedInputRef`, which will prevent dispatching events to a view that doesn't exist. If we made this change without the first then there's would be a race condition between calling blur on a TextInput and when that TextInput has been unregistered.

Summary:
A few recent imports have explicitly added ".js" to the end of their path. This prevents Metro from resolving platform-specific JS files, e.g. "Foo.android.js" or "Foo.windows.js" instead of "Foo.js".
React Native Windows provides its own implementation of files in a few cases where stock React Native will share them between Android and iOS. We hope to reduce/eliminate these long term, but requiring explicit ".js" files currently breaks us in a couple of places where we have custom implementations.
This change is a quick regex replace of ES6 and CommonJS imports in 'Libraries/" to eliminate ".js".

Summary:
The migration from classy to functional component partially broke controlled TextInput selections. This fixes it.
The nuance is that even though we have "event counters" sent from native, "onChange" and "onChangeSelection" are separate events;
so even if you receive new text and a new native event counter, your selection may be out-of-date. Incrementing the event counter
when sending selection events breaks text updates; and adding another native event counter seems like overkill. Instead, in JS, we statefully
keep track of (1) the native event counter, (2) whether or not the selection has been updated for that event counter.

Removing the requestAnimationFrame will cause the focus command to be sent in the same batch as starting screen transitions which fixes the issue.

Summary:
This is the first diff in the series. It removes Flow types for this feature to verify that we actually do not have any usages. After it lands, we will remove actual support on the native side.
There are several reasons why removing it is a good idea:
* There is no any evidence that this feature is actually useful. That was discussed several times (e.g. see T7936714) during RN lifetime and the overall consensus is: We need something else, something like sync `onChange` event instead of it.
* Supporting the previous point, it's not used (at least inside Facebook). I searched hard and I could find only one place where it's used: in the TextInput Example.
* To deliver more functionality we should lean towards W3C specs, this one is not W3C compliant.
* Supporting this Feature in Fabric is quite challenging, so I want to do it sooner than later.
* This feature was never documented.

Summary:
I wrote up a bunch of context for this in response to #27038 by fat. That comment is reproduced here in this commit message. You can see it in it's original contxt here: https://github.com/facebook/react-native/pull/27038
Okay, here is what I think is happening. For context, here is a diagram I have of how focus and blur propagates through the system. This might be interesting to refer back to as you go through the rest of my explanation.

ScrollView's scrollResponder is responsible for blurring text inputs when a touch occurs in the ScrollView but outside of the currently focused TextInput. The code for that is here:
https://github.com/facebook/react-native/blob/6ba2769f0f92ca75fb0eb60ccb8337920a9c31eb/Libraries/Components/ScrollResponder.js#L301-L314
This happens on `scrollResponderHandleResponderRelease` aka, touch up.
It checks for what the currently focused textinput is by calling `TextInputState.currentlyFocusedField()`.
That function is a JS variable that is being updated by calls to `TextInputState.focusTextInput` and `TextInputState.blurTextInput`:
https://github.com/facebook/react-native/blob/6ba2769f0f92ca75fb0eb60ccb8337920a9c31eb/Libraries/Components/TextInput/TextInputState.js#L36-L71
I added some console logs to those methods to see which ones are being called when running your repro (thanks for the repro!). **This is without your fix**
Click on and off:
```
// Click on input 1
focusTextInput input1
TextInput's _onFocus called
// Click on blank space
scrollResponderHandleResponderRelease blur input1
blurTextInput input1
TextInput's _onBlur called
```
Click on input1, then input 2, then off
```
// Click on input 1
focusTextInput input1
TextInput's _onFocus called for input1
// Click on input 2
focusTextInput input2
TextInput's _onBlur called for input1
TextInput's _onFocus called for input2
// Click on blank space
scrollResponderHandleResponderRelease blur input2
blurTextInput input2
TextInput's _onBlur called for input2
```
And now for the bug. Click on input 1, tab to 2, then off
```
// Click on input 1
focusTextInput input1
TextInput's _onFocus called for input1
// Tab to input 2
TextInput's _onBlur called for input1
TextInput's _onFocus called for input2
// Click on blank space
scrollResponderHandleResponderRelease blur input1
blurTextInput input1
```
Notice how `focusTextInput` was never called with input2 in the last example. Since this is the function that sets the `currentlyFocusedField` when we click on the blank space RN is trying to blur the first input instead of the second.
# The root cause
We are tracking the state of which field is focused in JS which has to stay in sync with what native knows is focused. We [listen to _onPress](https://github.com/facebook/react-native/blob/6ba2769f0f92ca75fb0eb60ccb8337920a9c31eb/Libraries/Components/TextInput/TextInput.js#L1103-L1107) and call `TextInputState.focusTextInput` in that handler. However, we don't currently have anything listening to other ways for an input to become focused (like tabbing) so it doesn't end up updating the `currentlyFocusedField`.
We have the same problem with blur that we actually fixed the same way you did here in this PR:
https://github.com/facebook/react-native/blob/6ba2769f0f92ca75fb0eb60ccb8337920a9c31eb/Libraries/Components/TextInput/TextInput.js#L1182-L1189
If you look back at my diagram at the beginning of this post, you'll notice the missing edge from `TextInput._onFocus` to `TextInputState.focusTextInput`. That's the problem. :)
The reason this solution works is because this function **is** the notification from native that an input was focused or blurred. This solution is *fine* because this updates the `currentlyFocusedID` but isn't great because it both sets that value and **calls the native code to focus or blur again**. Luckily the native code doesn't send an event back to JS if you try to blur an already blurred TextInput otherwise we'd have an infinite loop.
# The correct solution
The correct thing would probably be to have all of this tracking in native code and not in JavaScript code. That's a pretty big change though and very out of scope. Something for our team to keep in mind for the future.
A short term term solution would be to refactor `focusTextInput` and `blurTextInput` to pull out the part that sets the `currentlyFocusedID` that we could call from `TextInput` directly from `_onFocus` and `_onBlur`.
# ^This short term term solution is what this commit is doing.

Summary:
In React Native there are three types of "Native" components.
```
createReactClass with NativeMethodsMixin
```
```
class MyComponent extends ReactNative.NativeComponent
```
```
requireNativeComponent('RCTView')
```
The implementation for how to handle all three of these exists in the React Native Renderer. Refs attached to components created via these methods provide a set of functions such as
```
.measure
.measureInWindow
.measureLayout
.setNativeProps
```
These methods have been used for our core components in the repo to provide a consistent API. Many of the APIs in React Native require a `reactTag` to a host component. This is acquired by calling `findNodeHandle` with any component. `findNodeHandle` works with the first two approaches.
For a lot of our new Fabric APIs, we will require passing a ref to a HostComponent directly instead of relying on `findNodeHandle` to tunnel through the component tree as that behavior isn't safe with React concurrent mode.
The goal of this change is to enable us to differentiate between components created with `requireNativeComponent` and the other types. This will be needed to be able to safely type the new APIs.
For existing components that should support being a host component but need to use some JS behavior in a wrapper, they should use `forwardRef`. The majority of React Native's core components were migrated to use `forwardRef` last year. Components that can't use forwardRef will need to have a method like `getNativeRef()` to get access to the underlying host component ref.
Note, we will need follow up changes as well as changes to the React Renderer in the React repo to fully utilize this new type.
