LibWeb: Cache the first <base href> (in tree order) in Document

Browse source 
When parsing relative URLs, we have to check the first <base href> in
tree order (if one is available). This was getting *very* costly on
large DOMs with many relative urls.

This patch avoids all that repeated traversal by letting Document cache
the first <base href> and invalidating the cache whenever a <base>
element is added/removed/edited in the DOM.

The browser was stuck doing this for a *very* long time when loading
the ECMA-262 spec, and this removes that problem entirely.
