        Adds ValidityState.tooLong support for <input> and <textarea>.

        Introduces tooLong() in HTMLFormControlElement and it always returns false.
        HTMLInputElement and HTMLTextAreaElement overrides it and checks the text
        length and maxLength.  tooLong() should work only for `dirty' values.
        So, introduces m_isDirty flag for HTMLTextAreaElement, and
        !m_data.value().isNull() works as a dirty flag for HTMLInputElement.

        Renames parameter names of setMaxLength().
