pipeline: ipa: raspberrypi: Pass exposure/gain values to IPA though controls
When running with sensors that had no embedded data, the pipeline handler would fill a dummy embedded data buffer with gain/exposure values, and pass this buffer to the IPA together with the bayer buffer. The IPA would extract these values for use in the controller algorithms. Rework this logic entirely by having a new RPiCameraData::BayerFrame queue to replace the existing bayer queue. In addition to storing the FrameBuffer pointer, this also stores all the controls tracked by DelayedControls for that frame in a ControlList. This includes include exposure and gain values. On signalling RPi::IPA_EVENT_SIGNAL_ISP_PREPARE IPA event, the pipeline handler now passes this ControlList from the RPiCameraData::BayerFrame queue. The IPA now extracts the gain and exposure values from the ControlList instead of using RPiController::MdParserRPi to parse the embedded data buffer.
