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.

<details><summary>Uses iconforge so it does not take up much time during
init</summary>

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.

## About The Pull Request
I heard you liked commas.
## Why It's Good For The Game
Trailing commas make everyone happy!
## Changelog
Nothing anyone will notice besides downstreams adding to these lists
## About The Pull Request
As the title says.
`init_order` is no more, subsystems ordering now depends on their
declared dependencies.
Subsystems can now declare which other subsystems need to init before
them using a list and the subsystem's typepath
I.e.
```dm
dependencies = list(
/datum/controller/subsystem/atoms,
/datum/controller/subsystem/mapping
)
```
The reverse can also be done, if a subsystem must initialize after your
own:
```dm
dependents = list(
/datum/controller/subsystem/atoms
)
```
Cyclical dependencies are not allowed and will throw an error on
initialization if one is found.
There's also a debug tool to visualize the dependency graph, although
it's a bit basic:

Subsystem load ordering can still be controlled using `init_stage`, some
subsystems use this in cases where they must initialize first or last
regardless of dependencies. An error will be thrown if a subsystem has
an `init_stage` before one of their dependencies.
## Why It's Good For The Game
Makes dealing with subsystem dependencies easier, and reduces the chance
of making a dependency error when needing to shift around subsystem
inits.

* Adds lazyloading to the asset subsystems (#69454)
* Adds lazyloading to the asset subsystems
This currently applies only to spritesheets because of how monumentally
expensive they are.
If an asset is requested it will immediately be fully loaded, but
otherwise we slowly load them in with a separate subsystem.
This allows us to not hold up initialize with hair stuff. Saves roughly
33% (16 seconds with LOW_MEMORY_MODE) of initialize on my machine
My target is something closer to the 9 second init that had back in
2019, this is a good first step. Lets see how much more we can do yeah
lads?
