[Feature Request] Implement gamepad motion sensors on Android

[Nintorch]

Similarly to https://github.com/libsdl-org/SDL/issues/14497, motion sensors (accelerometer and gyroscope) are not available for controllers on Android without the HIDAPI driver. I think it should be possible to make them work, see https://developer.android.com/develop/ui/views/touch-and-input/game-controllers/controller-features

If at the moment nobody is interested enough to implement them, I can try to do that when I have enough free time (probably on the winter holidays :( )

Sure, go for it!
