Mech fabricator output direction can now be changed with a drag pull (#87828)

## About The Pull Request

See name, makes it consistent with all the other printing machines. For
some reason we have three different paths for all of them but
refactoring is out of scope for me.

Comes with updatepaths too

## Why It's Good For The Game

No more confusion with how to change the direction, it's the same as all
the other ones now.
