libcamera: ipu3: cio2: Return the FrameBuffer pointer used

When adding IPA plumbing to the IPU3 pipeline handler it will be needed
to track which raw buffer was queued to the CIO2 for a specific request.
Currently if using an internally allocated raw buffer the FrameBuffer is
not exposed outside the CIO2Device as it was not needed. Prepare for the
IPA by exposing which internal raw buffer is picked for each request,
later changes will associate this with a Request.
