The only API to add a parent/child relationship between existing entities is through commands, there is no easy way to do it from `World`. Manually inserting the components is not completely possible since `PreviousParent` has no public constructor. This PR adds two methods to set entities as children of an `EntityMut`: `insert_children` and `push_children`. ~~The API is similar to the one on `Commands`, except that the parent is the `EntityMut`.~~ The API is the same as in #1703. However, the `Parent` and `Children` components are defined in `bevy_transform` which depends on `bevy_ecs`, while `EntityMut` is defined in `bevy_ecs`, so the methods are added to the `BuildWorldChildren` trait instead. If #1545 is merged this should be fixed too. I'm aware cart was experimenting with entity hierarchies, but unless it's a coming soon this PR would be useful to have meanwhile.
