    Deprecate ClipboardFormatType::GetType()

    - ClipboardFormatType::CustomPlatformType() is another synonym and is
      more descriptive.
    - Strengthen the DCHECK to a CHECK and improve method comments.
    - Leave a forwarding stub for GetType() for now. It will be removed in a
      followup.
