Implement override.txt support for special tiles (#10140)
Add override targets for all special_tiles entries in node definitions, allowing texture packs to replace these textures. This makes overrides work properly with a variety of drawtypes.

The targets are named special1 through special6, covering the the current length of the special_tiles array.
