libcamera: pipeline: vivid: Generate and validate StreamConfigurations
Implement the support for Generating and Validating the streams the Camera can provide. Vivid is a simple case with only a single stream. Test the configurations can be generated and reported with cam -I: """ LIBCAMERA_LOG_LEVELS=Pipeline,VIVID:0 ./src/cam/cam -c 1 -I [232:02:09.633067174] [2882911] INFO IPAManager ipa_manager.cpp:136 libcamera is not installed.
