Dead raptors no longer get happy when petted or groomed (#84959)

## About The Pull Request

I have noticed that when I petted a raptor corpse I have found, it
started spinning and hearts appeared above it. Apparently, the same
happens if you wash them. This PR makes sure that dead raptors stop
spinning in their graves.

I decided to not to disable the happiness component's processing on
death, as the idea that the raptor's ghost looms over you, patiently
waiting to be revived is funny, and also encourages their revival to be
a priority.

This PR also removes a duplicate animal petting proc that has not
actually been hooked into anything.

## Why It's Good For The Game

Dead animals should consistently act as dead animals.
