Also, reset static state in destructors of interfaces.
Until now, new interfaces were being created for each repeated
getExtension() call to the Gnss interface. This was causing
asserts to fail which were checking for multiple
simultaneous instances of these interfaces.
Death notifications should still required to be created for all
interfaces including callback interfaces.

Test: On Angler, GPS location available on Maps. All interfaces other
than AGnssRil, AGnssNavigationMessage and GnssNi are functionally tested. AGnssRil and
AGnssNavigationMessage are not implemented by conventional GPS HALs in Google devices that would be
upgrading to O.
