Jacopo Mondi ee027781b4 libcamera: buffer: Store Request reference in Buffer ...

Add to the Buffer class methods to set and retrieve a reference to the
Request instance the buffer is part of.

As buffers outlive the Request they are associated with, the reference
is only temporary valid during the buffer completion interval (from when
the buffer gets queued to Camera for processing, until it gets marked as
completed).
