[Mojo Video Capture] Split interface BuildableVideoCaptureDevice into “device launcher” and “launched device”
This is a cleanup/simplification CL.
This CL is supposed to be a pure refactoring. There should be no changes to
existing behavior.
Changes in this CL:
* Split interface BuildableVideoCaptureDevice into interfaces
VideoCaptureDeviceLauncher and LaunchedVideoCaptureDevice.
* Split implementations accordingly.
* VideoCaptureController is freed from knowledge of
VideoFrameConsumerFeedbackObserver and VideoCaptureDeviceLauncher::Callbacks.
* Moved mock implementations to a separate file, since they are used by more
than one test.
This CL is part of the Mojo Video Capture work. For the bigger picture,
see [1] CL21.
