Support for SBAS and IRNSS satellite constellation

While running the renewed satelliteinfo example on Lenovo Tab Gen 4 devices, there
are warnings:

qt.positioning.android: : Unknown satellite system 2

Which means an unhandled constellation, corresponding to SBAS according to Android documentation

On a OnePlus 9 device there is:

qt.positioning.android: : Unknown satellite system 7

Which in turn corresponds with IRNSS, as per Android documentation

Adding support for these should be investigated. This includes checking the other applicable backends (gypsy, NMEA at least) and adding also a new public enum values. Also example apps need to be adjusted
