Tweaks ai escape_captivity behavior (#94224)

## About The Pull Request

Now: AI will break chairs they're buckled in
After PR: Ai will prefer to resist out of chairs if possible

Fixes #94222 , partially

Really I think this shouldn't be a subtree, orrrrr if it is it should be
enabled by combat.
It's weird that buckling a pet into a pet bed encourages them to get up
ASAP.
If a mob is completely docile or otherwise not trying to act, they
shouldn't freak out and break whatever they're sat in.

Alternatively pets need a behavior for seeking out a bed (but that's
more effort)

## Changelog

fix: AI mobs will prefer to resist out of simple buckles (like being sat
in a chair or bed) rather than try to break the chair.
