Ghosts stay in bellies (#15918)

* Ghosts stay in bellies

Ported a change to digestion from chomp:
Changed digestion death to place the characters ghost inside of the belly they died in. This allows them to be see the belly text still, be carried around and can even be moved between bellies (such as moved along with everything else to intestines, etc), or hear a final subtled message. Tested and seems to work fine here.

Ports these PRs: https://github.com/CHOMPStation2/CHOMPStation2/pull/3074 https://github.com/CHOMPStation2/CHOMPStation2/pull/4772 https://github.com/CHOMPStation2/CHOMPStation2/pull/7132

Plus one addition of my own to prevent it playing the ingestion sound upon the ghost being placed in the belly.

* Fixes the ghost's camera being stuck when transferring them to different bellies.

* Don't announce releasing observers

* Fix for ghosts being visible in examines
