Bloop 655b66bdd0 Adds automatic GAGS icon generation for mapping and the loadout menu (#90940)
Revival of https://github.com/tgstation/tgstation/pull/86482, which is
even more doable now that we have rustg iconforge generation.

What this PR does:

- Sets up every single GAGS icon in the game to have their own preview
icon autogenerated during compile. This is configurable to not run
during live. The icons are created in `icons/map_icons/..`
- This also has the side effect of providing accurate GAGS icons for
things like the loadout menu. No more having to create your own
previews.

this still applies:

Note for Spriters:

After you've assigned the correct values to vars, you must run the game
through init on your local machine and commit the changes to the map
icon dmi files. Unit tests should catch all cases of forgetting to
assign the correct vars, or not running through init.

Note for Server Operators:

In order to not generate these icons on live I've added a new config
entry which should be disabled on live called GENERATE_ASSETS_IN_INIT in
the config.txt

No more error icons in SDMM and loadout.

🆑
refactor: preview icons for greyscale items are now automatically
generated, meaning you can see GAGS as they actually appear ingame while
mapping or viewing the loadout menu.
