Fix: Cult construct can attack while their spells are on cooldown (All spells no longer have a Melee CD by default) (#68806)

Fixes #68779

#68382 Added a "melee cooldown" to ALL cooldown actions by default, which is something I wasn't sure about in the PR, but Space suggested it wouldn't affect anything. Turns out did affect some things

I instead have overridden all the new cooldown actions (Alien, spells, and some misc ones) to have a 0 second melee cooldown, allowing constructs and similar to attack and use spells freely
