LibWeb: Add BrowsingContext::container() to align with the spec

Browse source 
We already have a base class for frame elements that we call
BrowsingContextContainer. This patch makes BrowsingContext::container()
actually return one of those.

This makes us match the spec names, and also solves a FIXME about having
a shared base for <frame> and <iframe>. (We already had the shared base,
but the pointer we had there wasn't tightly typed enough.)
