Prosthetic Item arms no longer prevent ventcrawling: the remake (#93499)

## About The Pull Request
This is me picking up #93077 but with code changes relative to the two
new flags that Krysonism added in his PR, which unfortunately he never
finished.

## Why It's Good For The Game
Monkeys should be able to ventcrawl even if their left or right arm is
actually a chainsaw or armblade or whatever. See #93077

## Changelog
🆑 Krysonism
balance: prosthetic item limbs are no longer considered equipped items
for some purposes such as ventcrawling.
