Extract feed routes (#2269)

* Extract feed routes from invidious.cr
* Removes the deprecated route for /feed/top
* Deprecate /view_all_playlist & use /feed/playlists
* Move feed views into their own directory

* Add haltf method to halt current route context
* Change status_code + return blocks to use haltf

* Set appropriate response headers for RSS routes
