Refactor VideoCaptureManager::GetDeviceFormatsInUse()

VideoCaptureManager::GetDeviceFormatsInUse() [1] has below issues:

1. It unconditionally returns true and modifies a list of things when
it could just return the one thing it provides (when available).
2. Its implementation does not match the specification in its method-
level comment.

media/video_capture_manager.h?type=cs&l=156

This CL takes care of these issues.
