Anim: added BKE_object_moves_in_time(object) function

This function exposes the already-existing static `object_moves_in_time()`
function, and optionally recursively checks the parent object for
animatedness as well.

I also added checking `AnimData::overrides` to
`BKE_animdata_id_is_animated()`. This ensures that, apart from the optional
recursion to the parent object, the function has the same functionality.
