LibWeb: Move the navigable's cursor position to be owned by the document

Browse source 
Navigables are re-used for navigations within the same tab. Its current
ownership of the cursor position is a bit ad-hoc, so nothing in the spec
indicates when to reset the cursor, nor do we manually do so. So when a
cursor update happens on one page, that cursor is retained on the next
page.

Instead, let's have the document own the cursor. Each navigation results
in a new document, thus we don't need to worry about resetting cursors.

This also makes many of the callsites feel nicer. We were previously
often going from the node, to the document, to the navigable, to the
cursor. This patch removes the navigable hop.
