Subject: [PATCH] Make <input> close <option> and <optgroup>

Based on feedback in the <select> parser relaxation HTML spec PR, we
might want to close the <select> on these tags when parsing an <input>:
https://github.com/whatwg/html/pull/10557#issuecomment-2847093540

If the UseCounter shows that usage is low enough, then we could remove
this behavior.
