Update getGnssCapabilities() in LMS to include sub-HAL capabilities

Browse Source 
The GNSS capabilities in the gnss@2.0 HAL have been refactored
(b/128028791, b/127434062, b/128309220). The sub-HAL capabilities
in the top level IGnssCallback.hal have been moved into their
respective sub-HALs. Consequently, the getGnssCapabilities()
method in LocationManagerService is hereby modified to include
the capabilities from all sub-HALs and the top level HAL.

A new GnssCapabilities class needs to be added so that we don't
expose the implementation details of the capabilities (a Java
int bitmask of capability flags) to the LocationManager client.

Bug: 128913861
Test: TBD
