        Change text-based <input> types to the new shadow DOM model
        https://bugs.webkit.org/show_bug.cgi?id=54179

        By this change, text field inputs and textareas have one extra
        shadow node at the root of shadow trees.
        e.g. Before the change:
          <textarea> --(shadow-connection)-- <div> -- ...
        After the change:
          <textarea> --(shadow-connection)-- {#shadow-root} -- <div> -- ...

        The goals of this change are
        - Change to the new shadow DOM model, and
        - Minimize the patch size.

        We should use shadowPseudoId() in the new shadow DOM model, but the
        shadow elements in this patch don't use it in order to reduce the patch
        size.

        (input::-webkit-inner-spin-button):
         Add vertical-align in order to avoid the button affect the baseline.
