mojom: pipeline: ipa: rpi: Add fields for PiSP objects

Browse source 
Add the PiSP Frontend and Backend SharedMemObject file descriptors to
the ipa::init() call. This will allow the pipeline handler to pass these
objects to the IPA after construction.

Add a flag to indicate if buffer swaps are needed when starting the
ISP for the stitch block.
