How does an application register a TurboModuleManagerDelegate with ReactInstanceManager?
1. Call ReactInstanceManagerBuilder.setReactPackageTurboModuleManagerDelegateBuilder(ReactPackageTurboModuleManagerDelegate.Builder)
2. Override ReactNativeHost.getReactPackageTurboModuleManagerDelegateBuilder()

Summary:
We'll pass these ReactPackageTurboModuleManagerDelegate.Builders to ReactInstanceManager. ReactInstanceManager will then use these builders to initialize the TurboModule system. To allow TurboModules to work with RNTester, we have to switch RNTester over to using these Builders.

Summary:
Previously, owner(TurboModuleManager) used to depend on owner(ReactInstanceManager). Now, owner(ReactInstanceManager) depends on owner(TurboModuleManager).
**Rationale:** This allows ReactInstanceManager to create TurboModuleManager.

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
[iOS] [Fixed] - Fix Codegen silently failing when Yarn is not installed, or when Yarn v2 is active.
Pull Request resolved: https://github.com/facebook/react-native/pull/30781
Test Plan:
### Case 1 (no Yarn installed)
1. Ensure `yarn` is not present in PATH
2. Run Xcode build
3. Check that Codegen artifacts are produced
### Case 2 (Yarn v2 is used)
1. Ensure `yarn` is running in the v2 ("Berry") mode
2. Run Xcode build
3. Check that Codegen artifacts are produced

Tiny PR that removes an old orphaned `.nvmrc` file (added in 2018 and not touched since then).
Most likely the project does not work with Node.js 8.11.3 anymore. There is (no longer) a need to attempt to strictly enforce a specific version client-side. `package.json` _already_ declares

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.
## Changelog
[iOS] [Fixed] - Make codegen more reliable on iOS
Pull Request resolved: https://github.com/facebook/react-native/pull/30792
Test Plan:
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:
See comments. On iOS in Fabric, LayoutAnimations is only conditionally enabled; whereas on Android it's always enabled. That means for code on iOS that relies on the onComplete callback, there might be bugs.
Ensure the callback is always called on iOS by racing a timer with the animation completion.
This will be deleted before Fabric "ships" fully.
Impact is minimal since this change is scoped to only run on iOS and under Fabric.

Summary:
Refactors `RCTNeworking.ios.js` so that event registration does not get passed along to `NativeNetworkingIOS`. Instead, we go straight to `RCTDeviceEventEmitter` (which is what `NativeEventEmitter` ultimately does when `nativeModule` is not supplied).
This optimization reduces overhead of making network requests, and it is made possible because `NativeNetworkingIOS` does not actually do any meaningful work when `startObserving` is invoked.

`UpdateState` lambda can be called multiple times because of state auto-repeater. But previously we moved state data into the lambda and then moved it into constructor shared data constructor. If auto-repeater called update state lambda again, the data would be in invalid state.
To fix this, state data has to be copied into shared data constructor.
Background executor was more likely to kick trigger state auto-repeater, that's why the crash was happening in BE experiment.
State-autorepeater was enabled at the end of December. That explains why the crash started appearing in v301 (prior to 301, this crash was not happening).

Fixes an inconsistency that `AttributedStringBox` can get into.
Example of inconsitency:
After `AttributedStringBox` is moved (move constructor or move assignment operator), moved from `AttributedStringBox` needs to be set into blank state. Its mode needs to be `Value`, `opaquePointer_` should be nullptr and `value_` empty AttributedString. This was not the case before as the default move constructor and operator would leave `mode_` as `OpaquePointer` but ivar representing opaquePointer would be nullptr.

Summary:
The `Event` interface has been improved such that:
1. `getEventData` is now a default method on Event that returns null
2. `dispatch` has a default implementation that relies on getEventName() and getEventData()
3. `dispatchModern` can detect if surfaceId and event data are present; if not, it falls back to dispatch
This will dramatically ease future migrations: at some point in the (distant) future, we can simply delete RCTEventEmitter and
all use-cases will be supported by the current `Event` class without needing to introduce a 3rd transitional interface; and 99%
of all Event classes can be simplified, delet their `dispatch` implementation and need no further work.
At their core, all Events are simply: (1) a name, (2) data, (3) a target (surfaceId and tag). The interface now reflects that but still
allows for flexibility of the data and names being generated on-demand if necessary; but for the vast majority of Event classes, code
will be dramatically simplified.
I also migrate a single Event class, ContentSizeChangeEvent, to use this new method of dispatch.
