SmArtKar 3499727a6d Implements datumized embedding handlers in place of element-component-datum triad (#88511) 
## About The Pull Request

This PR completely rewrites our embedding system in favor of embedding
datum handlers which acts as containers for all embedding-related data
and logic.

Currently embedding logic relies on an element-component-datum triad,
where elements on the items handle embedding logic, singleton datums
store embedding data and components (which get assigned to ***mobs*** in
whom the item embedded) handle pain and the item being ripped out. How
do we access all the procs? By using comsigs as procs, which is really
bad. This code was written back in 2020 when DCS was hot stuff but in
hindsight this implementation was a mistake, as it heavily restricts
custom embedding behaviors unless you're willing to constantly run
GetComponent (bad, ugly, incarnation of evil)

This PR rewrites all that logic to be handled by lazyloaded
``/datum/embedding``, which is stored similarly to current
``/datum/embed_data``. Upon being requested, it is initialized and
assigned to a parent from whom all the logic is handled, from being
embedded to pain and having the item ripped out. On projectiles this
only handles one proc, after which it copies itself down to the shrapnel
item instead and runs the chain further from there.
Ideally, most embedding-related logic now should be handled purely
datum-side - in most cases items should not be hooking up to themselves
like they did before (unless said logic is for when the item is made
sticky or smth) and instead the code should be handled by the embedding
datum (see sholean grapes implementation in this PR). This should allow
us to do fancy stuff like syringe guns embedding syringes into targets
and injecting them that way, and fix some bugs along the way.

Closes #88115
Closes #87946

Also fixed a bug with scars not displaying when examined closely from
#86506 because i was in the area anyways
