8843111d - [Sanitizer] Option to fallback to stderr if unable to open logfile (#158687)

[Sanitizer] Option to fallback to stderr if unable to open logfile (#158687) Add the santizier option `log_fallback_to_stderr` which will set the logpath to `stderr` if there is an error with the provided logpath. We've seen this happen when process A has write permission to the logpath, but process B does not. In this case, we'd like process B to fallback to writing to `stderr`, rather than being killed.
