Coroner Update: Pickle-Eating Morbid Weirdo Obsessed with Death and Perfectionism (#76318)

This PR introduces a whole bunch of Coroner and Morbid related content.

Firstly, Morbid is now a mind trait, and specifically, coroners start
with it.

Coroners also have a liver trait that allows them to heal toxins (very
slowly) from eating pickles and drinking pickle juice. They also
can...drink formaldehyde. I guess. Dissections is thirsty work.

Coroners gain a whole set of special tools specifically for use in any
surgeries marked as interests of the Morbid. This is determined by the
``surgery_flag`` called ``SURGERY_MORBID_CURIOSITY``. Currently, these
surgeries are included;

dissections, autospies, revival surgery, plastic surgery, organ/feature
manipulations, amputations

To fit the theme, TRAIT_MORBID also applies the reduction to eye
snatchers.

While using their special tools, and the surgery is a morbid curiosity,
the coroner/anyone who is morbid gains a 30% speed boost! This stacks
with the dissection speed boost. Otherwise, the tools are just regular
tools with a special name (though the scalpel is better at killing
undead, because, you know, you're watching over the dead).

The coroner's special medkit, which is the only one you can get in a
round, can fit their autopsy scanners and tools. Anything that comes
standard with their kit can go back into it.

Anyone who is morbid can safely retrieve the secrets of the elephant
graveyard. The serrated shovel, notably, is a much better tool and
notably better at killing organics, but not inorganics (like the dead).
