lib/video-source: Add video_source_import_buffers
We need to be able to place encoded data into the sink device's bufs.
To facilitate that add a video_source operation that allows the source
to import buffers from the sink.
Add a .import_buffers() callback so that the libcamera-source can
access a sink's buffers.
