Android: Remove video recording functionality from the camera classes

There was an attempt to add MediaRecording functionality to the camera
classes, but it was never finished and never worked properly. This CL
removes the code for it. In the future, if offline video recording is
needed we should add it as a VideoSink instead of inside the camera
classes.
