Rename `BoneCollection::is_visible_effectively()` to `is_visible_with_ancestors()`. Soon a "solo" flag will be introduced, and the effective visibility of the bone collection will depend on that too. This particular function doesn't take that into account, though, and thus needs a rename. Note that this does NOT rename the RNA property `is_visible_effectively`. That will be updated when the "solo" flag is introduced to also take that into account. No functional changes. Pull Request: https://projects.blender.org/blender/blender/pulls/117414
