[M106][Android] Use CrashKeyString to tag FRE crashes

If Chrome is started and the FRE is not completed yet - tag crashes
happening in this session with "first_run": "yes". This is consistent
with iOS, where crashes from the first run are tagged with
"first-run": "yes". This information is helpful to analyze stability
of FRE-related launches and should give us more info about the flow
that led to a crash.
