Formatting: Allow KSES custom elements with hyphens

The W3C Custom Elements spec (http://www.w3.org/TR/custom-elements/#concepts) allows you to use your own custom DOM elements/tags. One of the main requirements is that the tag name "must contain a U+002D HYPHEN-MINUS character". This adjusts KSES to allow it.

Fixes #34105.
Props batmoo.
