Revert "Revert "Update GNSS Batching to use new GnssLocation with elapsed realtime (HAL)""

This reverts commit b3721a68f273c305ea8e151cd3a8c192605370fc.

Reason for revert: 
It appears that the build includes ag/6721678 but not ag/6762021 even though they both were submitted together. Hence the build errors.
