A recent update in the spec (https://github.com/whatwg/dom/pull/1079) introduced new rules for name validation of attribute, element, and doctype. This PR implements the new name validation rules in `components/script/dom/bindings/domname.rs`. The old XML name validation rules are not fully removed because there remains a few usage of it in `ProcessingInstructions` and `xpath`.
