pipeline: ipa: raspberrypi: Use IPA cookies

Pass an IPA cookie from the pipeline handler to the IPA and eventually back to
the pipeline handler through the setDelayedControls signal. This cookie is used
to index the RPiController::Metadata object to be used for the frame.

The IPA cookie is then returned from DelayedControls when the frame with the
applied controls has been returned from the sensor, and eventually passed back
to the IPA from the signalIspPrepare signal.
