nicbn c4648c9a82 Make pipe layers better, also some cleanups (#41664) 
* Layered pipes no longer stick out of their tile, also vents and other
  machines will always be in the middle of the tile.
* Layer manifold now looks like an adaptor.
* Some pipe mapping helpers were made into macros so maintianing things is
  easier.
* Some unused icons were removed.
* A lot of icons were added, so that pipe layering looks better.
* Layer manifold renamed to layer adaptor and resprited to look more like an
  adaptor.
