More improvements to come. In particular, this still iterates through Shadow DOM
in each_xbl_cascade_data, but that should be changed later. That allows to
cleanup a bunch of stuff and finally fix Shadow DOM cascade order.
We still rely on the binding parent to be setup properly in the shadow tree, but
that requirement can go away later (we can walk the containing shadow chain
instead).
This mostly focuses on removing the XBL binding from the Shadow host.
It'd be nice to do EnumerateShadowRoots faster. I think that should also be a
followup, if needed.

This also makes the rule map not process all the stylesheets for the document,
which would be a mess with shadow DOM.
Far from the final, ideal state, but hey, progress.

This commit adds class ServoStyleRuleMap which caches the mapping from
raw Servo style rule to Gecko's wrapper object.
It is a per-document object, and is added as an observer of document
when constructed, so that it updates data inside when possible.
For safety consideration, this change also makes ServoStyleRule support
weak pointer, and use weak pointer inside ServoStyleRuleMap.
