Andreas Kling 6d830e6335 LibWeb: Tie layout tree to a specific browsing context ...

Now that both the layout tree and browsing context are GC-allocated,
we can formalize their relationship a bit better by having layout
nodes keep a NonnullGCPtr to the browsing context.

This makes the previously-indirect link direct, removing an unpleasant
"how do we know the browsing context is alive" question when accessing
it from the layout tree.
