[android] Replace Oboe audio with SDL3 audio (#4338)

Supersedes #4335.

Replaces the Oboe audio backend with SDL3, since we already support it.
A few caveats:

- SDL defines a JVM OnLoad method already, so we have to instead hijack
  NativeLibrary for id_cache initialization
- This also means some internal fields in Double/Integer/Boolean (namely
  `value`) can't be accessed, so I switched those to methods for now.
- SDL Java sources are pulled in from the CI package.
- Since we can't use SDLActivity, `SDL.setupJNI()` handles everything
