[MIRROR] Adds neck-snapping to CQC and Sleeping carp [MDB IGNORE] (#2…

…5491)

* Adds neck-snapping to CQC and Sleeping carp (#79956)

## About The Pull Request
If you achieve a kill-grab on your target as a sleeping carp or CQC
user, you can use harm on their head to snap their neck, killing them
instantly.
## Why It's Good For The Game
Neck snapping is in line with that secret-agent/commando badassery that
sleeping carp and CQC emulate. If you are in a kill grab from a carp or
CQC user, you were probably dead anyways, so this shouldn't have large
balance implications.
## Changelog
:cl: itseasytosee
add: Sleeping carp/cqc users can now snap peoples necks by punching them
in the head while they are in a kill grab.
