[BOLT][NFC] Rename profile-use-pseudo-probes
The flag currently controls writing of probe information in YAML
profile. #99891 adds a separate flag to use probe information for stale
profile matching. Thus `profile-use-pseudo-probes` becomes a misnomer
and `profile-write-pseudo-probes` better captures the intent.
