Summary:
In an effort to simplify and clean up the `EventEmitter` abstractions in React Native, this removes `once()` and `removeCurrentListener()`. Across the Facebook codebase, there were only two callers of `once()` and no callers of `removeCurrentListener()`.
The same behavior can be achieved using:
```
const subscription = emitter.addListener('event', () => {
subscription.remove();
// ...
});
```
Changelog:
[General][Removed] - Removed `once()` and `removeCurrentListener()` fom `DeviceEventEmitter` and `NativeEventEmitter`.

Summary:
Renames `EventSubscription.js`, `EmitterSubscription.js`, and `EventSubscriptionVendor.js` to `_EventSubscription.js`, `_EmitterSubscription.js`, and `_EventSubscriptionVendor.js`, respectively.
This is to indicate that those files are implementation details and should not be directly referenced. Instead, the `EventSubscription` type exported from `EventEmitter.js` should be used.
The remaining stragglers that are importing `_EmitterSubscription.js` and `_EventSubscriptionVendor.js` after this commit will be cleaned up when `RCTDeviceEventEmitter` is refactored.

Summary:
Changes `EventEmitter.js` to be Flow-typed so that it can export an interface for `EventSubscription`. In order to retain the untyped-ness of `EventEmitter.js`, I moved the entire definition into an untyped `_EventEmitter.js` file (which I hope no one will try importing from).
This new interface will be used to replace all the current type imports of `EventSubscription` and `EmitterSubscription`.

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".
## Changelog
[General] [Fixed] - Do not explicitly include ".js" in Library imports

Summary:
The original reason for vendoring the fetch polyfill was to remove the default blob response type but this was reverted.
Here's a little history around the fetch polyfill and the blob issue:
- Original commit introducing the vendored polyfill: #19333, the goal was to fix a memory leak because our blob implementation doesn't release resources automatically. Not an ideal fix but since the issue was pretty severe and the infra for a proper fix was not in place.
- This introduced an issue when downloading images using `fetch` which was fixed by #22063 which re-added the default blob content type. However that re-introduced the original fetch memory leak.
- We have better infra now with jsi and I was able to get blob deallocation working, see #24405
Currently the vendored fetch polyfill is useless since it was changed back to the original version. We can just use the npm version again. I also updated to 3.0 which brings better spec compliance and support for cancellation via `AbortController`, https://github.com/github/fetch/releases/tag/v3.0.0.

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries/vendor` have been rewritten to use relative requires. Talking to cpojer, the vendored code in RN can be modified directly.
This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.
Closes#24769.

Summary:
Fixes a regression in 1f8b46a2fc. The internal subscription vendor uses a sparse array to track listeners, which makes listener removal fast. When querying listeners, the sparse entries need to be removed. `Array#filter` is a built-in way to do this -> linked to the JS spec, which explains this.

Summary:
Prepack does not understand how to use a random key as an object property. Instead, at build time, it generates a deterministic property name based on a deterministic seed for `Math.random()`.
Prepack would like to move away from this, and keep all the `Math.random()` unevaluated and left in the bundle.
Since this is the only usage of `Math.random()` that can't be handled by the abstract interpreter, it should be changed.
Note that the randomness is not required here at all, it just has to be *some* unique key.
