Guard Villagers

[CHANGE] make it compatible with 26.1.0 and any future versions

• [MAJOR] 21.1.0 port(special thanks to zzong8286-crypto on github for helping out with the majority of this)
• [CHANGE] guards can use spears and added bows and iron axes to guard equipment selection

• [CHANGE] stop guards from moving around slightly while patrolling
• [CHANGE] make it so return to village ai has higher priority than attacking mob ai so guards are able to return to the village more effectively

• [CHANGE] stop guards from moving around slightly while patrolling
• [CHANGE] make it so return to village ai has higher priority than attacking mob ai so guards are able to return to the village more effectively

• [CHANGE] hopefully reduces issues with guard pathfinding to patrol points (with help from hrmcngs)
  • If guards are continually stuck they will simply pause their patrol finding ai for a moment before reactivating their ai to walk back to their patrol point
