Core:Selector: Move jQuery.contains from the selector to the core module
The `jQuery.contains` method is quite simple in jQuery 4+. On the other side,
it's a dependency of the core `isAttached` util which is not ideal; moving
it from the `selector` the `core` module resolves the issue.
Closes gh-5167
