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
jquerygh-4395; this change restores it.

Closes jquerygh-5580
Ref jquerygh-5570
Ref jquerygh-4395
