chore(features) Add api_expose to remaining features (#74572)

- Add api_expose=False to features that aren't used in sentry or
getsentry frontend.
- Add api_expose=True to features that are used in getsentry UI, and
some that I missed last time.

This should improve the response time of organization details as we will
be checking fewer feature flags on each request.
