Update GNSS Batching to use new GnssLocation with elapsed realtime (framework)

The ElapsedRealTime field was added to the GnssLocation in
gnss@2.0 HAL to additionally report elapsed time since boot.
The IGnssBatchingCallback.hal@1.0 must be extended to use this
new version of GnssLocation so that the location reported in
gnssLocationBatchCb() method includes the ElapsedRealTime field.

Fixes: 128034260
Test: Tested the new GNSS Batching extension using default
      implementation, VTS test, and cuttlefish.
