Add GnssAntennaInfo framework APIs

Test: End to end test: run "atest GnssAntennaInfoRegistrationTest" on cuttlefish and watch "adb logcat | grep -i GnssAntennaInfo". Other tests:  atest GnssAntennaInfoTest, atest GnssAntennaInfoProviderTest, atest GnssManagerServiceTest, atest VtsHalGnssV2_1TargetTest, atest LocationManagerFineTest.
