Ports shared particle holders

About The Pull Request

Ports tgstation/tgstation#87892

Implements a shared holder particle system, somewhat inspired by Baystation12/Baystation12#34014 (thanks Kapu). Atoms can be assigned "shared" particles via add_shared_particles, with an optional "alternate" key passed as a second arg if you're planning to edit the returned particle holder (for example, color it like slimed status does). Removing is done via remove_shared_particles with an option to delete the shared holder if nothing is using it anymore (on by default). This system should be prioritized over normal particle holders when a lot of entities would be using a certain particle effect (like fires) as it conserves a lot of clientside performance.

Why It's Good For The Game

Less clientside lag.

Changelog

🆑 Absolucy, SmArtKar
refactor: Various status effects and objects now use a new "shared" particles system, which should considerably improve client performance when encountering entities with a lot of particle effects.

You probably want tgstation/tgstation#88048, tgstation/tgstation#88114 and tgstation/tgstation#88111 too while you're at it

@SmArtKar i kinda just ctrl+f'd through our code for particle usage, rather than cherry-picking the followups, as we seemingly haven't ported some of the previous stuff that added particles to stuff
