Start adding infrastructure to retrieve video frames as texture
We're using RHI here, as that's what we need for Qt Quick anyway.
You can now set a QRhi object on QVideoSink. This can then be
used internally to create textures of the required format instead
of memory buffers.
QVideoSurfaceFormat will now tell you how many planes are required
for the format, and you can retrieve the textures for each plane
from QVideoFrame.
