Pull Request resolved: https://github.com/facebook/react-native/pull/53374
This method was deprecated in React Native 0.79. We should be able to remove it without impact in 0.82.
I also verified that there are no users of this API in OSS.
There is also a 1:1 replacement for this API which is the other non-deprecated getDefaultReactHost() method.

Pull Request resolved: https://github.com/facebook/react-native/pull/53349
Follows feedback on D78904767, refactoring how we pass data to `PerfMonitorOverlayViewManager` to avoid API additions on `DevSupport`.
New interfaces under `com.facebook.react.devsupport.perfmonitor`:
- `PerfMonitorUpdateListener` is implemented by the view class to receive updates from the C++ `HostTargetDelegate`.
- `PerfMonitorInspectorTargetBinding` exposes an API on `ReactHostInspectorTarget` to send CDP actions down to C++ (stub for now).
- `PerfMonitorDevHelper` allows us to use the internal `ReactHostImplDevHelper` to expose the `ReactHostInspectorTarget` instance from the runtime.

When encountering embedded <Text> components, with the parent <Text> component setting event handlers, culling away the child <Text> components will break the assignment of the event handlers to the text spans on Android.
This diff disables view culling on <Text> components so that event handlers would be correctly assigned to the text fragments once rendered.

A new version of ktfmt broke the OSS CI build for React Native.
That's due to us running still on the older version of ktfmt, as the newer version hasn't been released yet.
I'm temporarly disabling the `ktfmtCheck` jobs because we primarly check formatting from within fbsource.

We have a microbenchmark for `ReactFabricHostComponent` vs. `ReactNativeElement` but the test code itself is so fast that a big part of its duration is just calling the test function (a noop is 300-500ns, while the duration of these benchmarks is between 800 and 1400ns).
Note that this affects all tests the same way, so the absolute difference in execution time in both tests was still accurate.
This changes how we execute the benchmarks so the test function runs the code under test multiple times and we then report the average of all the runs using the new `overriddenDuration` option.
