Add parser to support CSV location data

Bug: 213225295
Test: launch_cvd -cpus 16 -memory_mb 16192  --start_gnss_proxy
--gnss_file_path=/google/data/rw/users/yu/yuchenhe/input.txt (Running blue
dot in Google Maps)

Almost a cherry-pick but changed the data type from AIDL GnssLocation to
the HIDL type, since there are no AIDL GnssLocation Type in SC-V2.
