utils: v4l2-ctl: support V4L2_CAP_IO_MC in v4l2-ctl '--list-formats-*' commands
Add optional <mbus_code> arg to 'v4l2-ctl --list-formats-*' commands for capture, metadata and output devices. If <mbus_code> is given and the device has capability V4L2_CAP_IO_MC then list only the formats that matches the mbus code. The mbus_code is ignored for devices that don't use it or don't have the V4L2_CAP_IO_MC capability.
