Auto merge of #15931 - emilio:die-defaultvalues-die, r=mbrubeck

style: Kill SharedStyleContext::default_computed_values.

This is on top of https://github.com/servo/servo/pull/15928.

Now that cascade() gets a Device ref, we can use the default computed values
from there to avoid propagating that state all over the place.
