feat: Add StateWrapper to fbjni typings (#55288)

Summary:
In [Nitro](https://nitro.margelo.com), we support creating views using Fabric's view system.

We use `StateWrapper` (and `StateWrapperImpl`) from C++. While we can use `react::StateWrapperImpl` from C++, we had to define `StateWrapper` ourselves ([see `JStateWrapper.hpp`](https://github.com/mrousavy/nitro/blob/main/packages/react-native-nitro-modules/android/src/main/cpp/views/JStateWrapper.hpp))

`StateWrapperImpl` inherits from `StateWrapper` in Kotlin, but the same inheritance is not reflected in C++ via fbjni.

To fix this, we did some dirty static downcasting, which is not safe to do but worked.

## Changelog:

[ANDROID] [ADDED] - Add `StateWrapper` to C++ fbjni types

Pull Request resolved: #55288

Test Plan:
When you have a `StateWrapperImpl` in Kotlin, pass that to C++ via fbjni using the `jni::alias_ref<react::StateWrapper>` type. (Example; `SimpleViewManager.updateState(...)` gives you a `StateWrapper`)

Then try downcasting via `jni::dynamic_ref_cast<react::StateWrapperImpl>(...)`.

If both works, this PR works.
