Implement form-associated custom elements and their ElementInternals (#31980)
* FACEs work, setFormValue test is awful so now has _mozilla backup * 1. Impl Validatable in ElementInternals instead of HTMLElement. 2. Reuse the code in Validatable trait. 3. The form associated custom element is not a customized built-in element. * add some comments * support readonly attribute and complete barred from constraint validation * Addressed the code review comments * Updated the legacy-layout results * Fixed the WPT failures in ElementInternals-validation.html * Addressed the code review comments * Review suggestions * Fixed silly mistakes and update the test result outside elementinternals * update the test results --------- Co-authored-by: Patrick Shaughnessy <pshaughn@comcast.net> Co-authored-by: Martin Robinson <mrobinson@igalia.com>
