Integrate QAbstractVideoSurface API.

This introduces a QAbstractVideoSurface interface for implementing arbitrary
video outputs, and a QVideoFrame type.  Also included is the
QVideoSurfaceFormat class which is used to configure the input to a video
surface, and the QAbstractVideoBuffer class which allows QVideoFrames
to be constructed from non-native frame types.
