LibWeb: Add a FrameHostElement for frame/iframe common functionality

A FrameHostElement is an HTML element (<frame> or <iframe>) that may
have a content frame that participates in the frame tree.

This basically just moves code from <iframe> to a separate base class
so we can share it with <frame> once we implement <frame>.
