Andreas Kling 49ac0c2e24 LibHTML: Move layout root from HtmlView to Document ...

The layout root is now kept alive via Document::m_layout_root.
This will allow us to do more layout-related things inside the inner
layer of LibHTML without reaching out to the HtmlView.

I'd like to keep HtmlView at a slightly higher level, to prevent it
from getting too complex.

This patch also fixes accidental disconnection of the layout tree from
the DOM after doing a layout tree rebuild. ~LayoutNode() now only
unsets the DOM node's layout_node() if it's itself.
