[css-variables] Slight tweak to value space of CSS variables

Currently the value space of CSS variables is the "value" production
in the CSS 2.1 grammar, as specified here:
and defined here:

One detail that bothers me is that this production allows the CDO
and CDC tokens *inside* of (), [], or {}, but does not allow them at
the top level of the value.

I think we should change this, and change the value space of
variables from:
  [ value | CDO S* | CDC S* ]+
