chore(hybridcloud) Rename model silo annotations (#69921)

Rename `control_silo_only_model` and `region_silo_only_model` to have
simpler names. We scrapped the idea of models that live in both silo
modes a long time ago and this naming convention is no longer helpful.

If folks are onboard with this rename I'll update all the model
definitions in sentry and getsentry.
