Small and tiny mobs no longer trigger the squeak component (#89100)

## About The Pull Request

This prevents mobs with `MOB_SIZE_SMALL` or `MOB_SIZE_TINY` from
triggering squeak sounds on crossed. Simple enough.

Also made the cooldown use the cooldown macros.

## Why It's Good For The Game

Small or tiny mobs are, well, tiny, and wouldn't really be able to
trigger the same kinda reaction.

Also sound spam is universally bad, and this gets rid of another method
of sound spam.
