Room server changes for room versions (#930)

Browse source 
* Rearrange state package a bit, add some code to look up the right state resolution algorithm

* Remove shared

* Add GetRoomVersionForRoomNID

* Try to use room version to get correct state resolution algorithm

* Fix room joins over federation

* nolint resolveConflictsV2 because all attempts to break it up so far just result in it being awfully less obvious how it works

* Rename Prepare to NewStateResolution

* Update comments

* Re-add missing tests
