        Refactor HTMLInputElement: Move parseToDouble() and
        parseToDateComponents() to InputType.
        https://bugs.webkit.org/show_bug.cgi?id=46965

        Introduce BaseDateAndTimeInputType, which is a super class of
        date, datetime, datetime-local, month, time, and week types.

        No new tests. Just a refactoring.
