GNSS Service handling System death

Stops all GNSS HAL operations, as system doesn't need them any more:
  normal, measurements, navigation message, batching
Update default implementation to resend capabilities and system info
  and corresponding VTS to enforce
Minor fixes completing the location check
Softens GPS VTS to pass with no signal (still applies better checks
  if there is signal)

Bug:36291274
Bug:36066672
Bug:35678469
Bug:35799723
Fixes:36291274
Fixes:36066672
Fixes:35799723

Test: VTS test passes, GPS stops after system server is killed
  Basic GPS tests (including delete Xtra) work (before VTS is run)
