Summary:
Original commit changeset: 91eb08181f82
Original diff: D16940181
The original commit removed the gating logic to enable the "fix" to T48583301. However, v236 was burned, and v237+ no longer had this gating, making it impossible to measure the impact of the fix.
This diff reverted the original gating removal until we confirm the fix in prod. Note: this is to be picked to RC v238 (but will have merge conflict for sure, will send a separate diff for the branch).

Summary:
To help determine how severe this issue is, put the fix behind a MC.
We will only pick the parent diff to the RC branch so that the fix immediately goes to master and we don't have to worry about fixing this any further.

Summary:
@public
CADisplayLink strongly holds onto its target, so you have to use a weak proxy object to pass the target into the CADisplayLink.
Previously we passed a weak-self point (i.e. weakSelf) but this did not have the intended effect, since the pointer to self would still be passed to CADisplayLink, and thus it would hold onto the RCTUIImageViewAnimated strongly.
So is weakSelf doing anything other than using self?
It is but it's very minor and not useful. In the case that the object got de-allocated between assigning self to weakSelf and creating the CADisplayLink, then we would pass a nil target. This is actually impossible though because we are running an instance method, so self is implicitly retained! So semantically it is something different but in practice it is the same as passing self through.
Notes:
* This system was added originally in https://github.com/facebook/react-native/pull/24822
* https://github.com/facebook/react-native/pull/25636 then "enabled" this system by deprecating existing approach

Summary:
This is my proposal for fixing `use_frameworks!` compatibility without breaking all `<React/*>` imports I outlined in https://github.com/facebook/react-native/pull/25393#issuecomment-508457700. If accepted, it will fix https://github.com/facebook/react-native/issues/25349.
It builds on the changes I made in https://github.com/facebook/react-native/pull/25496 by ensuring each podspec has a unique value for `header_dir` so that framework imports do not conflict. Every podspec which should be included in the `<React/*>` namespace now includes it's headers from `React-Core.podspec`.
The following pods can still be imported with `<React/*>` and so should not have breaking changes: `React-ART`,`React-DevSupport`, `React-CoreModules`, `React-RCTActionSheet`, `React-RCTAnimation`, `React-RCTBlob`, `React-RCTImage`, `React-RCTLinking`, `React-RCTNetwork`, `React-RCTPushNotification`, `React-RCTSettings`, `React-RCTText`, `React-RCTSettings`, `React-RCTVibration`, `React-RCTWebSocket` .
There are still a few breaking changes which I hope will be acceptable:
- `React-Core.podspec` has been moved to the root of the project. Any `Podfile` that references it will need to update the path.
- ~~`React-turbomodule-core`'s headers now live under `<turbomodule/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- ~~`React-turbomodulesamples`'s headers now live under `<turbomodulesamples/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- ~~`React-TypeSaferty`'s headers now live under `<TypeSafety/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511040967.
- ~~`React-jscallinvoker`'s headers now live under `<jscallinvoker/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- Each podspec now uses `s.static_framework = true`. This means that a minimum of CocoaPods 1.5 ([released in April 2018](http://blog.cocoapods.org/CocoaPods-1.5.0/)) is now required. This is needed so that the ` __has_include` conditions can still work when frameworks are enabled.
Still to do:
- ~~Including `React-turbomodule-core` with `use_frameworks!` enabled causes the C++ import failures we saw in https://github.com/facebook/react-native/issues/25349. I'm sure it will be possible to fix this but I need to dig deeper (perhaps a custom modulemap would be needed).~~ Addressed by https://github.com/facebook/react-native/pull/25619/commits/33573511f02f3502a28bad48e085e9a4b8608302.
- I haven't got Fabric working yet. I wonder if it would be acceptable to move Fabric out of the `<React/*>` namespace since it is new? �
## Changelog
[iOS] [Fixed] - Fixed compatibility with CocoaPods frameworks.
Pull Request resolved: https://github.com/facebook/react-native/pull/25619
Test Plan:
### FB
```
buck build catalyst
```
### Sample Project
Everything should work exactly as before, where `use_frameworks!` is not in `Podfile`s. I have a branch on my [sample project](https://github.com/jtreanor/react-native-cocoapods-frameworks) here which has `use_frameworks!` in its `Podfile` to demonstrate this is fixed.
You can see that it works with these steps:
1. `git clone git@github.com:jtreanor/react-native-cocoapods-frameworks.git`
2. `git checkout fix-frameworks-subspecs`
3. `cd ios && pod install`
4. `cd .. && react-native run-ios`
The sample app will build and run successfully. To see that it still works without frameworks, remove `use_frameworks!` from the `Podfile` and do steps 3 and 4 again.
### RNTesterPods
`RNTesterPodsPods` can now work with or without `use_frameworks!`.
1. Go to the `RNTester` directory and run `pod install`.
2. Run the tests in `RNTesterPods.xcworkspace` to see that everything still works fine.
3. Uncomment the `use_frameworks!` line at the top of `RNTester/Podfile` and run `pod install` again.
4. Run the tests again and see that it still works with frameworks enabled.

Summary:
The goal of this PR is to improve the pipeline currently used for displaying GIFs / animated images on iOS. It is achieved by not holding all of the decoded frames in memory at the same time, as well as happily releasing existing memory whenever possible. This code is a simplified version of what you would find in SDWebImage (it is nearly 1:1, with unsupported or uneeded things removed). By adopting this API, it also allows classes conforming to RCTImageURLLoader or RCTImageDataDecoder to return any decodable UIImages conforming to RCTAnimatedImage and have improvements to memory consumption. Because RCTAnimatedImage is just a subset of the SDAnimatedImage protocol, it also means that you can use SDWebImage easier with Image directly.
A nice to have would be progressive image loading, but is beyond scope for this PR. It would, however, touch most of these same parts.
## Changelog
[iOS] [Fixed] - Substantially lower chances of crashes from abundant GIF use
Pull Request resolved: https://github.com/facebook/react-native/pull/24822
Test Plan: TBD. (but i am running a version of this in my own app currently)
