Partial sparks boilerplate reduction (#26081)

* Partial sparks boilerplate reduction

- Lots of obects are making `/datum/effect_system/spark_spread`, setting
them up, firing them, and then not qdeling them afterwards.
- Makes a `do_sparks` global proc that takes the same arguments as `set_up`
and then calls `start` and then `qdel`
- Switches a bunch of things to use this proc
- Makes emitters keep their own spark_spread datum around, since they
spark so damn much.
- Also makes some things use timers and ports some things to Initialize.

* Compilation
