Selector: Properly deprecate `jQuery.expr[ ":" ]`/`jQuery.expr.filters`

Those APIs have formally been deprecated since `3.0.0`, but they never made its
way into the deprecated module.

`jQuery.expr[ ":" ]` has been removed when Sizzle got inlined into Core in
gh-4395; this change restores it.

Closes gh-5580
Ref gh-5570
Ref gh-4395
