As reported in #138173, enabling `-ftime-report` adds pass timing info to the stats file if `-stats-file` is specified. This was determined to be WAI. However, if one intentionally wants to put timer information in the stats file, using `-ftime-report` may lead to a lot of logspam (that can't be removed by directing stderr to `/dev/null` as that would also redirect compiler errors). To address this, this PR adds a flag `-stats-file-timers` that adds timer data to the stats file without outputting to stderr.
