Chris Olszewski ceae48c0f7 Add pfh labels to targets
Summary:
While it would be better to be able to do all of the ownership metadata at the Buck macro level, that proved to be more work than expected.

This diff adds the corresponding pfh label to all targets in `xplat/js/react-native-github` that have a Supermodule label. Once the migration is complete the Supermodules labels will be able to be removed.

Scott Kyle 30cb78e709 New bridging API for JSI <-> C++
Summary:
This adds  `bridging::toJs` and `bridging::fromJs` functions that will safely cast to and from JSI values and C++ types. This is extensible by specializing `Bridging<T>` with `toJs` and/or `fromJs` static methods. There are specializations for most common C++ and JSI types along with tests for those.

C++ functions and lambdas will effortlessly bridge into JS, and bridging JS functions back into C++ require you to choose `SyncCallback<R(Args...)>` or `AsyncCallback<Args...>` types. The sync version allows for having a return value and is strictly not movable to prevent accidentally moving onto another thread. The async version will move its args onto the JS thread and safely call the callback there, but hence always has a `void` return value.

For promises, you can construct a `AsyncPromise<T>` that has `resolve` and `reject` methods that can be called from any thread, and will bridge into JS as a regular `Promise`.

Scott Kyle 6a9497dbbb Move some classes to new bridging library (#33413)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/33413

This moves `CallbackWrapper` and `LongLivedObject` into a new "bridging" library. This library is mostly intended for use by the native module system, but can also be used separately to "bridge" native and JS interfaces through higher-level (and safer) abstractions than relying JSI alone.
