The Medical Stasis Refactoring (#21311)

This PR implements a variety pack of new interactions for Medical Stasis
(stasis beds, stasis bags, and cryogenics), which should broadly extend
their utility. Not all of it is necessarily a good thing to have around,
such as for instance stasis slowing down the rate at which the liver
removes toxins. A few more organs have by extension been time
differentiated to allow for this change to take place.

As a general rule of thumb, most organ effects that are handled "per
second" are proportionally slowed down by the stasis rating of a given
source of medical stasis. This can be a good or a bad thing depending on
the context.

**Good effects of Stasis:**
- Slowing down appendicitis.
- Reducing the damage organs take per second from most per-second
sources.
- Making kidneys and livers deal less dangerous effects to their owner
when severely damaged.
- (Not in this PR, but was done in a previous PR): Brains lose BA
slower.

**Bad effects of Stasis:**
- Organs also heal slower from all per-second sources, this includes
chems. So while they take less damage, they're also taking less healing.
- The liver's rate at which it filters the blood is reduced. You get to
stay black-out drunk for 10x longer if placed in stasis.
- (Not in this PR, but was done in a previous PR): Brains heal their BA
slower.
