Bug 1799343 - Simplify XUL popup handling. r=TYLin

Browse Source 
* Make non-menulist popups just absolute positioned top-layer items.
 * Simplify menulist popups to just be static-positioned items under
   nsMenuFrame.

We need to keep kPopupList only for nsMenuFrame. In the future it can be
removed, see TODO in xul.css
