[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 Signed-off-by: crueter <crueter@eden-emu.dev> - [x] I have read and followed the [Contribution Guidelines](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/CONTRIBUTING.md#code-contributions). - [x] I have read and followed the [AI Policy](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/docs/policies/AI.md) - [x] I have read and followed the [Coding Guidelines](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/docs/policies/Coding.md) to the best of my ability. ------------------- Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/4338 Reviewed-by: Lizzie and Samuel <lizzie@eden-emu.dev> Reviewed-by: MaranBr <maranbr@eden-emu.dev>
