style: [css-nesting] Do a first pass at parsing nested rules mixed with declarations
Plumb everything up. This factors out declaration and rule parsing so
we share the code with the regular declaration parser.
This could be made a bit nicer in the future. We need to decide what to
do for @page and @keyframe (it seems conditional rules inside ought to
work, but that's not so easy because per spec we create a nested style
rule).
But this is a first pass that passes a good chunk of the tests. There
are other fixups to cssom, and I think some of the tests we fail are
actually wrong...
