Iron Golem Watchtower

In villages, there should be a new structure called the iron golem watchtower/base, where you can find a large door (or air gap), an iron golem, a chest with a few iron ingots/an almost broken anvil, and have it be the place where new golems spawn in a village. If there is not an iron golem base in a village, it will spawn randomly in the village. I think this would be a good addition to make it easier to locate where iron golems will spawn, so you could make a farm, or just have that knowledge.

The building will not spawn golems in it if the spawning space has blocks in it, if the blocks below the spawning space are leaves or scaffolding, or if a raid is occurring. (The golems would spawn near raiders to help the raid.)

The golems would spawn under the same rules as they currently do, just if the structure is available they spawn there.
