[MIRROR] [TEST-MERGE FIRST] Allows all limbs to be dismembered and significantly refactors wounds [MDB IGNORE] (#23407)

* [TEST-MERGE FIRST] Allows all limbs to be dismembered and significantly refactors wounds

* ah fuck it

* test

* edaawdawd

* Revert "edaawdawd"

This reverts commit 47be710fe61a1f4ca79212b29b3e88bf05ec9a3a.

* nothing but sheer hatred

* freaawd

* dzfxg

* Fixing some diffs here while we are at it.

* These are deprecated and should be removed
