android: Add RGB LED support for joysticks.

[MAJigsaw77]

This PR implements the ANDROID_JoystickSetLED by using the LightsManager API introduced in Android 12 (API 31).

• Detects RGB-controllable lights during joystick enumeration.
• Opens and maintains a LightsSession for each RGB-capable controller.
• Caches RGB light references to avoid repeated filtering.

I tested this implementation on a regular PS4 controller.

Closes #14497
