LPS-44122 Add new property "escape" to AppViewSearchEntryTag to control escaping

We sometimes escape "title" and "descrption" and sometimes don't in the source where use this taglib.

It can cause problems, as the taglib currently always does escape, but the HtmlImpl#escape method is not idempontent.
LPS-44122 Apply new Summary pattern to AppViewSearchEntry taglib
LPS-44122 Apply to Search portlet
LPS-44122 Apply to Web Content Search portlet
LPS-44122 Pass arguments without esacping to the taglib in portlets - let the taglib take care of it
