Add PULL_WEAPON monattack and use in relevant areas

[b3brodie]

Summary

Infrastructure "Add PULL_WEAPON monattack and use in relevant mods"

Purpose of change

Most cases of PULL_METAL_WEAPON are currently used in situations where they shouldn't actually care if the weapon is metal or not. Add new monster attack that doesn't care about the item material and switch these cases over.

Describe the solution

Basically reuse the pull_metal_weapon code but cut out all the segments related to material checking.
Switch old monattacks over if they shouldn't care about material.

Describe alternatives you've considered

Instead of expanding hardcoded monattacks I'd suggest moving it/both over to the JSON mattack infra - that lets you modify the attack on a per-monster basis and makes deprecating monattacks easier down the line.
