libcamera: ipa: Pass a set of controls and return results from ipa::start()

Browse source 
This change allows controls passed into PipelineHandler::start to be
forwarded onto IPAInterface::start(). We also add a return channel if the
pipeline handler must action any of these controls, e.g. setting the
analogue gain or shutter speed in the sensor device.

The IPA interface wrapper isn't addressed as it will soon be replaced by
a new mechanism to handle IPC.
