pipeline: raspberrypi: Set the ISP Output1 to 1/4 resolution if unused

In preparation for fast colour denoise, set the low resolution ISP output stream (Output1) to a 1/4 resolution of the application requested stream (Output0). This only happens if the application has not requested an additional YUV or RGB stream. We also constrain this 1/4 resolution to at most 1200 pixels in the largest dimension to avoid being too taxing on memory usage and system bandwidth. Also switch the default StreamRole::VideoRecording to YUV420 to allow fast colour denoise to run.
