Stop cleaning the cache of a post's children. Ancestors are no longer cached against the post object, which means this kind of walking is unnecessary. It is also prohibitively expensive with large hierarchies.

We need to remove post_ancestors non-persistent caching for this. get_post_ancestors() can simply rely on the caching of get_post() instead. Previously, it was a direct query, hence the extra layers of caching and clearing.

Child cache clearing stays in wp_delete_post() as children get a new parent.

fixes #11399.
