Add more PPatchManager patch locations (#525)

Add two new available settings for the `RunAt` for `PPatchManager` patches:
* `DetailsScreen.OnPrefabInit` - For registering custom SideScreenContents
* `Db.PostProcess` - For patching after all buildings, entities and other prefabs have been fully created
