style: Slim down SharedStyleContext.

Browse source 
This slims down SharedStyleContext, in preparation for a few things.

First, I would like to eventually move the stylist to the document in Servo, in
order for it to hold the StyleSheetSet.

Also, this gets rid of a fair amount of overhead while creating it in stylo.

Fixes bug 1363245.
