Summary:
This PR fixes a few issues with the Appearance API (as noted here https://github.com/facebook/react-native/issues/28823).
1. For the Appearance API to work correctly on Android you need to call `AppearanceModule.onConfigurationChanged` when the current Activity goes through a configuration change. This was being called in the RNTester app but not in `ReactActivity` so it meant the Appearance API wouldn't work for Android in newly generated RN projects (or ones upgraded to the latest version of RN).
2. The Appearance API wasn't working correctly for brownfield scenarios on Android. It's possible to force an app light or dark natively on Android by calling `AppCompatDelegate.setDefaultNightMode()`. The Appearance API wasn't picking up changes from this function because it was using the Application context instead of the current Activity context.
3. The Appearance API wasn't working correctly for brownfield scenarios on iOS. Just like on Android its possible to force an app light or dark natively by setting `window.overrideUserInterfaceStyle`. The Appearance API didn't work with this override because we were overwriting `_currentColorScheme` back to default as soon as we set it.

Summary:
When there are multiple sticky headers, ScrollViewStickyHeader should push up the header above it when it gets to the top.
This behavior was accidentally changed in D21948830 (https://github.com/facebook/react-native/commit/fa5d3fb6b8c561b749f3e86316d06543a52dcc1c) when this component was fixed to work in Fabric.
This diff added a new variable `_shouldRecreateTranslateY`, which determines whether the `translateY` value should be recreated on render. `_shouldRecreateTranslateY` was not being set to true during `setNextHeaderY`, so the next header's Y value was never accounted for at render.

Summary:
Hermes has a way to set up a callback that is invoked when a fatal error
such as Out of Memory occurs. It is a static API that should be called at
most once, so it uses `std::call_once` to achieve that.
The fatal error handler is simple, it just uses glog to log an error message
to logcat, then aborts (using `__android_log_assert`).
The reason is typically very helpful for understanding why `hermes_fatal` was called.

Summary:
Since iOS 14 refresh control is sometimes visible when it shouldn't. It seems to happen when it is removed and added back to the window. This repros easily when using react-native-screens with react-navigation tabs. Inactive tabs are detached from the window to save resources.
Calling endRefreshing when refresh control is added to the window fixes the layout. It will also be called on first mount where it is not necessary, but should be a no-op and didn't cause any issues. I also decided to call it for all ios versions, although it is only needed on iOS 14+ to avoid forking behavior more.

RN Tester is using an old version of Flipper. This will help testing regressions in the latest version (which is installed when starting a new project). This also fixes an issue where libevent is incompatible between the one in flipper and when using hermes on iOS. To fix it I changed to use the version published on cocoapods instead of using a local podspec (see https://github.com/facebook/flipper/issues/1916).

Summary:
Currently, Codegen bash wrapper (`generate-specs.sh`) for Xcode invokes JS-based Codegen tooling via `yarn --silent node <...>`. This breaks both:
- when Yarn is not installed (if NPM is used), for obvious reasons
- when Yarn v2 ("Berry") is active
This PR changes the way `generate-specs.sh` locates `node` executable to the following algorithm:
- use the path provided in the `NODE_BINARY` env var
- if `NODE_BINARY` env var is not defined, find `node` with `command -v node`
## Changelog

1. Ensure `yarn` is not present in PATH
2. Run Xcode build
3. Check that Codegen artifacts are produced

Summary:
This addesses a few issues I noticed while migrating my app to the new build-time codegen on iOS.
1. I noticed random failures because of codegen on iOS. This is mostly due to the fact the codegen output files are not specified in the xcode script. The only reason it works relatively fine currently is because the codegen output is inside the input files directory. This has the side effect of causing files to be regenerated every build, then causes all core modules to be recompiled which adds up a significant amount of time to rebuilds. To fix this I added the generated files to the script phase output and moved the FBReactNativeSpec dir outside of the codegen source (Libraries). I moved it to the React directory as this seemed to make sense and is where a lot of iOS files are as well as the core modules. Note this might require internal changes. This removes the circular dependency between our build phase input and output so consecutive builds can be cached properly.
2. Add `set -o pipefail` to the xcode script, this helped propagate errors properly to xcode because of the `| tee` pipe so it fails at the script phase and not later with a header not found error. Also add `2>&1` to pipe stderr to stdout so errors are also captured in the log file.
3. Add the `-l` flag to the bash invocation to help finding the yarn binary. With my setup yarn is added to the system PATH in my user .profile. Adding this file will cause bash to source the user environment which xcode scripts does not by default. I think this will help with most setups.
4. If yarn is not found the `command -v yarn` would make the script exit without any output because of the -e flag. I made a change to ignore the return code and check later if YARN_BINARY is set and have an explicit error message if not.
[iOS] [Fixed] - Make codegen more reliable on iOS
Pull Request resolved: https://github.com/facebook/react-native/pull/30792

Tested various project states to make sure the build always succeeds in RN tester:
- Simulate fresh clone, remove all ignored files, install pods, build
- Build, delete FBReactNativeSpec generated files, build again
- Build, build again, make sure FBReactNativeSpec is cached and not rebuilt
- Make the script fail and check that xcode shows the script error logs properly

Summary:
The codegen helper script, `generate-specs.sh`, is being used to generate code for the FBReactNativeSpec and React-Fabric/rncore pods. The script now supports overriding several defaults by setting the following environment variables:
- SRCS_DIR: Path to JavaScript sources, defaults to $RN_DIR/Libraries/
- LIBRARY_NAME: Defaults to FBReactNativeSpec
- MODULES_OUTPUT_DIR: Defaults to Libraries/$LIBRARY_NAME/$LIBRARY_NAME
- COMPONENTS_LIBRARY_NAME: Defaults to rncore
- COMPONENTS_OUTPUT_DIR: Defaults to ReactCommon/react/renderer/components/$COMPONENTS_LIBRARY_NAME
The CocoaPods codegen integration has been updated to take advantage of these.
**Example CocoaPods usage:**
```
# packages/rn-tester/NativeModuleExample/RNTesterSpecs.podspec
Pod::Spec.new do |s|
s.name = "RNTesterSpec"
# ...
use_react_native_codegen!(s, { :srcs_dir => __dir__, :modules_output_dir => __dir__ })

Summary:
Consolidate CocoaPods codegen scripts under a single `use_react_native_codegen!` method in `react_native_pods.rb`.
This is the first step towards making the codegen scripts library-agnostic. There are still a handful of hardcoded assumptions in place (e.g. the output directory structure, the use of a separate directory for components), but with some work one would be able to add codegen support to arbitrary CocoaPods podspecs.
The codegen script no longer takes a CODEGEN_PATH argument, and will instead attempt to use the local react-native-codegen package if available, and fallback to using the node_modules/react-native-codegen package if not.
## Usage
The `use_react_native_codegen!` method has two arguments:
- `spec`, a pod [Specification](https://www.rubydoc.info/github/CocoaPods/Core/Pod/Specification) object.
- `options`, an optional object. Supported keys:
- `:srcs_dir`, the path to your JavaScript sources. Your native module or component specs should be located somewhere in this directory.

Summary:
Original PR contents:
This pull request updates the Podspecs and associated build scripts, and some source files so they build on OSS. RNTester now compiles with `fabric_enabled` again.
The following changes have been made:
* Various spots that were pointing to the old `ReactCommon/fabric` location have now been updated to `ReactCommon/react/renderer`
* Files that were attempting to use internal FB header `FBRCTFabricComponentsPlugins.h` were changed to use `RCTFabricComponentsPlugins.h`
* `RCTFabricComponentsPlugins` in OSS was updated to include the `Image` fabric component (thanks tsapeta)
* Replaced old `generate-rncore.sh` build script with new `generate-rncore.js` script which does not require `flow-node` and uses the `react-native-codegen` API directly, so there is no longer any need for an interim `schema-rncore.json` file.
* Updated Yoga podspec which wasn't fully synced with changes from the main Yoga repo
* Updated Fabric podspec with additional needed subspecs
Additions to PR by hramos:
* Replaced use of generate-rncore scripts with the original generate-native-modules-specs.sh script, which is now generate-specs.sh and supports both codegen for Native Modules and Components now (TurboModules/Fabric).
* Codegen now runs at build time as part of the Xcode build pipeline instead of as part of `pod install`. The build script is injected by the FBReactNativeSpec pod, as the pod is part of both Fabric and non-Fabric builds.

Summary:
The TurboModuleUtils.h includes "folly/Optional.h" which is not used and creates an unnecessary dependency on Folly.
In this PR we remove this unnecessary include.
It is required for the https://github.com/microsoft/react-native-windows/pull/6804 where we add an experimental support for the C++ TurboModules. While the C++ TurboModules use the same JSI and TurboModule code defined in react-native, we provide a layer that let them to work over the ABI-safe Microsoft.ReactNative.dll boundary. The RNW Nuget distribution with DLL files includes a few source files to create native/turbo modules that work through the ABI-safe API. The TurboModuleUtils.h is one of such files. By removing the dependency on Folly we reduce requirements for the native module code. After this PR is merged we will remove the fork of the TurboModuleUtils.h added in https://github.com/microsoft/react-native-windows/pull/6804.

Summary:
When building React Native application in Release mode for an iPhone Simulator _and_ targeting `armv7`, Xcode will build all architectures (due to `ONLY_ACTIVE_ARCH` set to `false`, unlike in Debug mode). As a result, Xcode will try building for `i386` (32-bit iPhone Simulator), which fails as we don’t build Hermes binaries for `i386`.
Fix is to disable `i386`, since it is not supported by `Hermes` and certain `Folly` features.
## Changelog
[IOS] [BREAKING] - `i386` architecture will be automatically disabled when Hermes is being used. This might be potentially breaking for your workflow if you target `armv7` devices, as you will no longer be able to test on the simulator.
[IOS] [FEATURE] - Replace `flipper_post_install` with `react_native_post_install` hook. Will automatically detect if Flipper is enabled.

Right now, running a React Native application with Xcode 12 in Release mode on an iPhone Simulator will fail with something like below:
> [some file path], building for iOS Simulator, but linking in object file built for iOS, file '[some file path]' for architecture arm64
The best explanation of this issue has been provided by alloy in https://github.com/facebook/react-native/issues/29984:
> This issue has started coming up with Xcode 12 and support for the new ARM based Macs, as `arm64` now no longer can be assumed to _only_ be for iOS devices. This means Xcode 12 will now also build for `arm64` simulator SDKs and it has become ambiguous if an arch slice in a prebuilt binary is meant for a simulator or device.
>
> In any case, for now this means that you can configure your Xcode project to exclude `arm64` when building for any iOS simulator SDK.
This PR implements aforementioned workaround.
