Summary:
This commit adds documentation to two methods of BackHandler API, addEventListener and removeEventListener. Despite being a simple change, it helps to keep the documentation consistent.
I have tested the `./website` locally, the changes look similar to some other components such as `NetInfo`.

Summary:
This usage of `...` currently causes BackHandler to silently become non-functional when a `Symbol` polyfill is used.
Why?
- The `[...obj]` operator implicitly calls the object's iterator to fill the array
- react-native's internal `Set` polyfill has a load order issue that breaks it whenever a project uses a `Symbol` polyfill
- This means that when `BackHandler` tries to `[...set]` a `Set` of subscriptions the result is always an empty array instead of an array of subscriptions
Additionally it's worth noting that the current code is also wastefully inefficient as in order to reverse iterate over subscriptions it:
- Clones the `Set` (which fills it by implicitly running the set's iterator)
- Uses `[...set]` to convert the cloned set into an array (which also implicitly runs the iterator on the clone)
- Finally reverses the order of the array
----
This code fixes this problem by replacing the use of multiple Set instance iterators with a simple `.forEach` loop that unshifts directly into the final array.
I've tested this by opening the repo's RNTester app on Android and tvOS ensuring that the back handler works before changes, the application crashes when I introduce an error (to verify my code changes are being applied to the app), the back handler works and after changes.

Summary:
Importing `react` modules from `react-native` has been deprecated since 0.25 so I think it's safe to remove it now since everyone has migrated their code and it is now well know and documented that you import from different packages. This finishes the spring cleanup of `react-native-implementation.js` :)

Summary:
If tracking is enabled and the sampling check passes on a scroll or layout event,
we compare the scroll offset to the layout of the rendered items. If the items don't cover
the visible area of the list, we fire an `onFillRateExceeded` call with relevant stats for
logging the event through an analytics pipeline.
The measurement methodology is a little jank because everything is async, but it seems directionally
useful for getting ballpark numbers, catching regressions, and tracking improvements.
Benchmark testing shows a ~2014 MotoX starts hitting the fill rate limit at about 2500 px / sec,
which is pretty fast scrolling.
This also reworks our frame rate stuff so we can use a shared `SceneTracking` thing and track blankness
globally.

Summary:
The PR description has been updated to reflect the new approach.
**Breaking Change Summary**
On Android, the following properties now return a different number:
- `Dimensions.get('window').fontScale`
- `Dimensions.get('screen').fontScale`
- `PixelRatio.getFontScale()`
This is a breaking change to anyone who was using these properties because the meaning of these properties has now changed.
These properties used to return a value representing font scale times density ([`DisplayMetrics.scaledDensity`](https://developer.android.com/reference/android/util/DisplayMetrics.html#scaledDensity)). Now they return a value representing just font scale ([`Configuration.fontScale`](https://developer.android.com/reference/android/content/res/Configuration.html#fontScale)).
**PR Description**
This PR changes a few things:
- Correctly exposes the font scale to JavaScript as `Dimensions.get('screen').fontScale`. UIManager was exporting `DisplayMetrics.scaledDensity` under the name `fontScale`. How

Summary:
On Android with dev mode on, we're seeing a regular SIGSEGV when pushing a lot of animation declarations over the bridge. We tracked this down to being not specific to animations, but the crash is caused in `deepFreezeAndThrowOnMutationInDev`.
Specifically: the provided object to freeze is modified while looping, replacing the current key access to a getter/setter. After the modification, JSC crashes during retrieval of the next key - but only when there are a lot of events passing over the bridge.
We have a hunch that this is due to a bug in JSC object enumeration but did we not look into it further yet. Any help here is welcome. The JS code seems all right at first sight and shouldn't cause a segmentation crash.
The workaround in this PR is to retrieve the keys first from the object and then looping over that array. In our app and in a reduced app test case this fixes the crash.
If needed I can provide the reduced app test case. It's really tricky to make a test for this as it requires to be run

Summary:
The MessageQueue has a _debugInfo object where it stores debug information associated with each callback. The size of this structure is currently unbounded.
It looks like the code attempted to restrict _debugInfo to a fixed number of entries but due to a logic bug, it leaked around 30 entries for every 1 entry it cleaned up.
This change limits the _debugInfo object to around 30 entries.

(Since it’s a niche feature it didn’t seem to me that full backward compat is necessary so I just removed old hooks. This won’t cause crashes—it’s just you won’t get events in Systrace if you use new React but old RN.)

Summary:
**Motivation**
In iOS you cannot dismiss alerts by clicking outside of their box, while on Android you can. This can create some inconsistency if you want to have identical behavior on both platforms. This change makes it possible for Android apps to have irremovable/required alert boxes just like in iOS.
This adds an additional parameter to the Alert method. The way to use it is by providing an object with the cancelable property. The cancelable property accepts a boolean value.
This utilizes the Android DialogFragment method [setCancelable](https://developer.android.com/reference/android/app/DialogFragment.html#setCancelable(boolean))
**Usage example**
```js
Alert.alert(
'Alert Title',
null,
[
{text: 'OK', onPress: () => console.log('OK Pressed!')},
],
{
cancelable: false
}

Summary:
This diff
- creates `XHRInterceptor` to intercept all XMLHttpRequest network operations in React Native by monkey-patching.
- enables `XHRInterceptor` in RN development tool "inspector".
This interception and inspector tool work well on both Android and iOS. And this supports interception on any network API based on XMLHttpRequest, especially the Fetch API.
By now, we can intercept 12 information fields of a XMLHttpRequest including method, url, data sent, status, response type, response size, requestHeaders, responseHeaders, response, responseURL, responseType and timeout.
Follow-up:
- Will add UIs in the inspector on top of this diff, to display all the network operation information. (Not in this diff just to make this shorter)
- Will extend this to gather other valuable information towards one XMLHttpRequest.
- Should support other network request APIs like WebSocket.
