Android: Add initialize() function to VideoCapturer interface
This CL moves some arguments, e.g. the camera thread, from the startCapture() function to a new initialize() function. These arguments are constant during the lifetime of the VideoCapturer, and are not changed for different startCapture() calls. Setting them once allows for simplifications in the code.
This CL also fixes a bug for camera2 where pendingCameraSwitchSemaphore might not be released when switchEventsHandler is null.
In camera1, the handler lock and 'cameraThreadHandler == null' check is replaced with an atomic boolean to check if the camera is stopped.
