nit: we could move this to `utils` if you think it could be useful for other
code paths in the future

Review Comment:
We do `AppBuilder(update_perms=False)` to avoid needing the db on startup
and use the cli to update permissions. We could also use `FAB_UPDATE_PERMS` to
control this behaviour also.
Following the same pattern we could create a new config flag to avoid
seeding the themes at app startup, and move this to `superset init` for example.
I'm also thinking about `register_sqla_event_listeners` that won't register
any listeners if we don't have a request context, and having a request context
is not expected on app initialization, so these listeners won't be registered
if the db uri contains `["nouser", "nopassword", "nohost", "nodb"]` and
`TAGGING_SYSTEM` is `True`
