[MDB IGNORE] Adds a map lint against using dir-var and icon-var edited windoors (#81272)

## About The Pull Request
Title.

Another big updatepaths PR thats been on my radar for awhile.

The dir banned var edit is self explanatory. However, I banned
icon_state from them as well as there are a big handful of windoors that
are either regular, and look like security doors, OR are their mirrored
counter part (a south right door var edited to look like a south left
door).

## Why It's Good For The Game

Avoid mapping sins like this
