Add gnssRequestLocationCb to IGnssCallback.hal and injectBestLocation
to IGnss.hal

- add the gnssRequestLocationCb to IGnssCallback.hal, with a boolean
flag to supply with or without GNSS information, to request location for
fast TTFF (or error recovery).

- correspondingly add the injectBestLocation to IGnss.hal for the
location provider to inject the location.
