Support certain mobs holding items

[Arnuh]

This does not include undead mobs that wear swords/armor, for that visit #98

• Wither Skeleton (Stone Sword)
• Pillager (Crossbow)
• Skeleton/Stray(Bow)
• Enderman (Almost any Block)
• Fox (Any Item?)
• Vex (Stone Sword)

[ ] Also Vexes too. They can hold any block in their hands/player head on their helmet slot (confirmed to work on disguises so pets should be, not required though

Looks like Vex do hold a stone sword by default so I'll add that to the list.

Technically any mob can probably hold items(Or at least tools/weapons)? Especially any 'normal' mobs with arms but I'm not focusing on that for this issue as it's technically not normal behavior.

If they hold an item, they should somewhat support any item. Players would be required to supply an item for them (if thats possible)
