[READY] Bespoke Datum Mats (#55296)

* Bespoke Material Backend

- Adds support for bespoke materials:
  - Reimplements [/datum/material/var/id]
  - Ports GetIdFromArguments from SSdcs
  - Adds a wrapper define for GetMaterialRef
  - Adds [MATERIAL_INIT_BESPOKE]
  - Adds [/datum/material/proc/Initialize]
- Does not actually add any bespoke materials

- [ ] TODO: Code docs
- [ ] TODO: Actually adding bespoke materials

* Some has_material procs and cleaning up some spaghetti

- Adds a pair of has_material procs for use in checking whether a given atom has a given material

* Adds meat

- Adds bespoke meat variants
  - Does not make them accessible
- Shuts up the linter

* Implements bespoke meat

- Makes the material container preserve bespoke materials
- Makes the sheetifier accept bespoke materials
- Makes the autolathe accept bespoke materials
- Makes the gibber produce bespoke meats

* Makes butchering produce bespoke meats

This is jank and really needs to be folded into a unified butchering and gibbing system

* Material documentation

- Adds, fixes, and touches up some documentation

* Material container insertion callback

- Changes the proc used to expand the material container's material list ot a proc used to check whether a material fits into a material container
- Instantiating new materials is no longer O(n) relative to the number of autolathes in existence.

* Makes processing meat conserve materials

- Makes bespoke meat carry over into meatballs

* Makes preserving custom materials an option

- Implements the ability to turn preserving custom materials _off_ for processor recipes

* Fixes all bespoke materials of the same type using the same singleton

- We use ids now, not just types.

* Makes the fat sucker produce bespoke meats

- Because consistency is good.

* Fixes autolathes merging bespoke stacks into normal stacks.

* Makes the callback to test materials for holdibility optional

- @Floyd

* GetMaterialRef -> GET_MATERIAL_REF

- We capitalize macros.

* Removes an extraneous callback

- Makes the sheetifier use functionality I didn't notice I implemented a few commits ago.

* Makes mob and species meat null compatible

* Fixes the ore silo

- The ore silo had really snowflake material handling that has been brought in line with the rest.
- The materials should show up in the correct order.

* Fixes minor lathe bugs

- Fixes stack_traces caused when lathes tried to fetch materials using reagent typepaths
- Fixed the selective reagent disposal topic. I have no idea how long this has been broken.

* Various documentation fixes

- Clarified a couple comments
- Removes an extraneous ?. operator
- Fixed mat floor tiles having bugged reagent temperatures

* More fixes

-/datum/material/meat/mob -> /datum/material/meat/mob_meat
- Adds atom typecheck to material containers.

* Fixes old typepaths
