Modify GnssLocationProvider to use Treble Gnss HAL 

Test: GPS functionality tested in binderized and pass-through modes on
Angler. All interfaces except AGnssRil, GnssNavigationMessage and
GnssNi. AGnssRil and AGnssNavigationMessage are not implemented by conventional
GPS HALs in Google devices that would be upgrading to O.
