[Search][Homepage] Remove usage (#194870)

## Summary

Removing search home usage from serverless search and enterprise search.
The search home page project is on hold while we re-assess requirements.
Until we know when we are starting that back up I'm removing the feature
flagged usage to simplify other work. When we spin this back up usage
will likely be different anyway with other projects like onboarding and
the updating navigation refactor in enterprise_search.
