Masayuki Nakano aa01224f4d Bug 2033732 - Make HTMLEditUtils::IsReplacedElement() stop using HTMLEditUtils::IsFormWidgetElement() r=m_kato 
A form widget element does not mean it's a replaced element. So, it
should check each tag name instead. Additionally, it's the last user of
`HTMLEditUtils::IsFormWidgetElement()` so that we can get rid of it.
