## 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.
## Changelog

refactor: Refactored subsystem initialization
/🆑
* Adds MC initialization stages. Earlier stages can fire while later ones init. Fixes tgui chat reconnection banner showing during init. (#66473)
* Adds MC initialization stages. Earlier stages can fire while later ones init.
Removes TICK_LIMIT_MC_INIT config for barely doing anything to speed up init and being inconvenient to work with if fires and inits can happen at the same time.
* Adds MC initialization stages. Earlier stages can fire while later ones init. Fixes tgui chat reconnection banner showing during init.

* Fixed spelling of possession, separate, and cemetery (#63203)
Just fixes some spelling for gangs. I also fixed misspellings for "posession" to "possession". Fixed "seperate " to "Separate" Fixed "Cemetary" to "Cemetery"
* Fixed spelling of possession, Separate, and Cemetery

* Splits init profiles into a seperate log file (#62545)
* Splits init profiles into their own file, so we can better track where pain points come from.
After all there's no point in knowing that sprite sheets generate 32 seconds of overtime during init if you
only care about inround, or vis versa.
(I'm tired of people freaking out about blends that are only done during init)
* Whoops
* Splits init profiles into a seperate log file
