Nuke Limb Processing (#22814)

Limbs make up roughly half of the "Per additional player" processing
overhead, while Organs make up most of the other half.
Not every organ is an easy candidate for "Event-only processing", but
external limbs are significantly easier to do so.

So this PR makes it so that External Limbs no longer require Processing
unless an event happens that would justify them requiring processing.
Which SIGNIFICANTLY reduces the overall additional cost to the
Processing subsystem per player that joins the server.

Oh and I also made the Appendix and Kidneys not require constant
processing. The Appendix will only process if it is hit by an
Appendicitis event, and the Kidneys will only process if they are either
damaged, or you get poisoned.
