[MIRROR] Stairs DLC: Buildable stairs, material datum staircases, fall up a staircase [MDB IGNORE] (#16925)

* Stairs DLC: Buildable stairs, material datum staircases, fall up a staircase (#70504)

Adds a few new types of stairs, and makes stairs buildable within rounds.
Also removes the terminator sprite variation for stairs, because its basically unused and really not needed with plane cube multiz.
