[css-grid] Update <fixed-size> syntax

The syntax for <fixed-size> has been updated on the spec:
https://drafts.csswg.org/css-grid/#typedef-fixed-size

New syntax is:
  <fixed-size> =
    <fixed-breadth> |
    minmax( <fixed-breadth> , <track-breadth> ) |
    minmax( <inflexible-breadth> , <fixed-breadth> )

This means that it's enough to have one <fixed-breadth>,
it doesn't matter if it's as minimum or maximum.
Before it was required that the minimum was fixed.

Updated test to check the new expected behavior.
