LPS-52309 - Web Form portlet is not accepting html code in the Options text field

this issue is caused by duplicate Html Escape.

1)first escape is in "view.jsp",second escape is in the "com.liferay.portal.kernel.xml.simple.Element.java",the method is "_formatText".

2)only one place is still escaped,the reason is that when sending the email,we should escape it. the logic is not the same.
