Add Android native API: CreateJavaVideoSource

Browse Source 
Adds Android native API for creating VideoTrackSourceInterface objects
that can be fed frames using VideoCapturer.CapturerObserver.

NativeCapturerObserver is moved out of VideoSource because it will now
be used without a VideoSource. It now takes a pointer to
AndroidVideoTrackSource directly instead of VideoTrackSourceProxy.

VideoSource and NativeCapturerObserver JNI code is moved away from
androidvideotracksource.cc to their own files. This allows using
AndroidVideoTrackSource independently.
