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.

We are preparing to allow video sources whose data is generated in
userspace. To this end, add a fill_buffer function to video_source.

We would like to be able to set the frame rate for video sources. This
patch adds a set_frame_rate op for video sources, along with a wrapper
to call video sources' set_frame_rate functions.

Split the project into a UVC gadget library and a test application. To
avoid rolling out a custom build system, switch to CMake.
