CameraEnumerationAndroid: Add getSupportedFormats() implementation using android.hardware.camera2

CameraEnumerationAndroid: Add getSupportedFormats() implementation using android.hardware.camera2

Enumerating using android.hardware.camera2 is 10x faster than enumerating using android.hardware.camera, but they don't list exactly the same formats. android.hardware.camera2 support higher resolutions for some cameras, and also different framerates.

Should we do this an all versions or should we have a version check here?

The version check is in Camera2Enumerator, so it will be catch-22 for native
code that wants to ask if Camera2Enumerator is supported, i.e. we need to load
the class in order for native code to query Camera2Enumerator.isSupported().
