ardupilot: added GNSS_SVINFO message

[tridge]

so we can display what satellites are being used ping @giacomo892 This will be a msg requested by the GCS when the UI is open to display sat info

More information is needed in how to distinguish constellations in the information, as well as the band, as the CNo isn't the same between L1/L2/L5....
