Move UseCounter to CSSParserContext

This refactoring adds an extra field to CSSParserContext, which
makes it the only object given to BisonCSSParser.

This change doesn't solve the mysterious lifetime of UseCounter.
It is a good step in this direction as it makes more explicit how
we inherit the UseCounter by removing several default arguments
inside the CSS code.
