Summary:
This diff fixed an edge case that event dispatching is failed after pre-allocation of a view and before the view is mounted.
When a cached image is loaded, we will dispatch the event to JS immediately. This is could happen after the view is created during pre-allocation phase, when the event emitter is not instantiated yet. In that case, we will see [an error](https://github.com/facebook/react-native/blob/main/ReactAndroid/src/main/java/com/facebook/react/fabric/FabricUIManager.java#L927) and the event will effectively be ignored.
To fix that we introduced a queue in this diff for those events. They will be dispatched in order when the view is mounted and the event emitter is non-null.

This patches a loophole in the logic that caused some operations to execute immediately and some to be deferred, even within the same render loop. This caused the non-queued operations to be executed out of order. Instead, if an operation is created and a queued exists, we just push the operation to the end of the queue so ordering is preserved.

Summary:
Sometimes this._scrollMetrics.offset is 0 even after initial scroll is triggered, because the offset is updated only upon _onScroll, which may not have been called in time for the next computation of the render limits. Thus, there is a window of time where computeWindowedRenderLimits calculates undesired render limits as it uses the offset. This results in 2 extra rerenders of the VirtualizedList if an initial scroll offset is applied, as the render limits shifts from the expected bounds (calculated using initialScrollIndex), to the 0 offset bounds (calculated using computeWindowedRenderLimits due to offset = 0), back to the expected bounds (onScroll triggers recalculation of render limits via _updateCellsToRender).
This issue was introduced in https://www.internalfb.com/diff/D35503114 (https://github.com/facebook/react-native/commit/c5c17985dae402725abb8a3a94ccedc515428711)
We cannot rely on this._hasDoneInitialScroll to indicate that scrolling *actually* finished (specifically, that _onScroll was called). Instead, we want to recalculate the windowed render limits if any of the following hold:
- initialScrollIndex is undefined or is 0
- initialScrollIndex > 0 AND scrolling is complete
- initialScrollIndex > 0 AND the end of the list is visible (this handles the case where the list is shorter than the visible area) <- this is the case that https://www.internalfb.com/diff/D35503114 (https://github.com/facebook/react-native/commit/c5c17985dae402725abb8a3a94ccedc515428711) attempted to address

Summary:
The `utils/build-apple-framework.sh` script uses the ruby runtime to load `hermes-engine.podspec`, and in the process it will load the Core CocoaPods gem to parse the podspec file.
Since the podspec file uses Pod::UI to print logs, and the CoreUI gem is not loaded when `build-apple-framework.sh` accesses `hermes-engine.podspec`, we would get a warning due to Pod::UI not being defined.
This change will only use Pod::UI when it is defined, therefore limiting it to only executing when `hermes-engine.podspec` is loaded as part of the normal `pod install` build process.

Summary:
Fixes https://github.com/facebook/react-native/issues/30708.
When given the `--port` option to the `npx react-native run-ios` command, [the React Native CLI passes the `RCT_METRO_PORT` variable when calling `xcodebuild`](https://github.com/react-native-community/cli/blob/ada951606e52ad98346cd72beeb15b56ceda8b7c/packages/platform-ios/src/commands/runIOS/index.ts#L552).
This used to adjust the port used when building on iOS, but this appears to have stopped working when the xcodeproj configuration was removed in favor of CocoaPods ([link, load the diff for React.xcodeproj](https://github.com/facebook/react-native/commit/79a7828b91b405de7399cd8cdc1aaaf610ce9d75#diff-43a2b2682727878049c3283b9361d9ad94964b63105fda6a834ba23baa5b471bL5199-L5205)).
This change re-adds the preprocessor definition that was used to pull the environment variable in, and now the `--port` flag works again.

Test Plan:
1. Using an example project generated from the 0.68.1 template, I modified `node_modules/react-native/React-Core.podspec` to have the same changes.
2. Deleted my project's `ios/Pods` folder and re-ran `bundle exec pod install`
3. Ran `yarn ios --port=9900` and verified that the app is connected to Metro, and check again with a refresh of the app.
4. Verified that I saw traffic on port 9900 when refreshing the app with `sudo lsof -i :9900`
5. Stopped the app and tested `yarn ios` without a port, and used `lsof` again to ensure it was using the default port `8081` again
I also ran the iOS tests locally and they passed.

Summary:
During debugging of undesired behavior using VirtualizedList with initialScrollIndex, it was found that zoomScale was sometimes undefined, which resulted in elementsThatOverlapOffsets returning not being able to find the frame at the given offsets.
This does not cause any unexpected behavior when scrolling from the top, as the first item index in VirtualizedList is always calculated to be 0; however, when we set initialScrollIndex, the frame calculations are incorrect, resulting in wasteful re-renders of the VirtualizedList as it renders every frame (row) from the top.

I'm updating the versioning schema of `react-native-codegen` to use minor instead of patch versions.
Historically we used to use a version as `0.0.15` and incrementally bump it.
Today, we had to do released a patched version of `react-native-codegen` for React Native 0.68.
Therefore, we're moving to use a versioning scheme as `0.<RN-VERSION>.x` which gives more flexibility and allows us to follow-up on specific version of the codegen for every RN version, should we need to.
`react-native-codegen` 0.70 is essentially a re-publishing of 0.0.16 from `main`

Summary:
Cherry picking https://github.com/facebook/react-native/pull/33707 to main branch
This change is extending the changes made by alespergl to reduce the file paths and command lengths of ndk build commands
Essentially we are shortening the length of the source files by using relative paths instead of absolute paths as enumerated by the wildcard expression
This commit is extending the fix by including all the new modules introduced into RN for the new architecture, including the generated modules.
We are also reverting the ndk bump as ndk23 is crashing frequently when building RN with new arch. The reduced file paths lengths ensures the ndk bump is not required for relatively short application paths.
Fix building RN with new architecture on Windows boxes by using relative paths for C++ sources
