[Changelog][Internal]
The initial intent was to try and use `unique_ptr` instead of `shared_ptr`, however turns out it complicates code more than it's worth it, so I ended up just factoring the repeated complex parts of the corresponding code to make it easier to reason about.

[Changelog][Internal]
Adds ability to invoke an async JS callback from a C++ native module, as a task with priority.
This will allow native modules to schedule less important calls to JS thread with lower priority. One example use case is feeding collected perf metrics back to JS.

Pull Request resolved: https://github.com/facebook/react-native/pull/35385
In OpenSource builds folly:: types are not always easy to consume.
With butter:: we actually allow consumers to opt-into other/non folly:: types (by providing a custom butter:: implementation).
This change adds a butter::function for that purpose.
It is especially useful for react-native-windows which prefers Mso::Functor over folly::Function.
You can use it by setting those compiler flags:
-DBUTTER_FUNCTION_OVERRIDE_INCLUDE=<functional/functor.h>
-DBUTTER_FUNCTION_OVERRIDE=Mso::Functor
std::function is no option as it is not move-only and we can't wait till 2025 > https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p0288r9.html

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`.
