Add type, limit, offset, min_id, max_id, account_id to search API (#10091)

* Add type, limit, offset, min_id, max_id, account_id to search API

Fix #8939

* Make the offset work on accounts and hashtags search as well

* Assure brakeman we are not doing mass assignment here

* Do not allow paginating unless a type is chosen

* Fix search query and index id field on statuses instead of created_at
