Summary:
This adds the *option* for C++ TurboModules to use a `*CxxSpec<T>` base class that extends the existing (and unchanged) corresponding `*CxxSpecJSI` base class with code-generated methods that use `bridging::calFromJs` to safely convert types between JSI and C++. If a type conversion cannot be made, then it will fail to compile.

fbshipit-source-id: 58b34533c40652db8e3aea43804ceb73bcbe97a5
Summary:
This adds `bridging::callFromJs` that can call class instance methods with JSI arguments and will automagically convert types to the types expected by the method, or otherwise will fail to compile. The same type conversion back to JSI applies as well for the return value, if there is one.
This will allow C++ TurboModules to more easily define their interface in terms of C++ types instead of having to interact with JSI directly for everything, though it remains possibles for JSI values to pass through if that's what a given method wants.

fbshipit-source-id: 1f9caadeefa6d4023f679e95f3decc64d156b3f0
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`.

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.
