Remove the support for “hover: on-demand” and “any-hover: on-demand” media queries. After this change, a pointing device that used to satisfy the “on-demand” value would satisfy the “none” value instead.

The “on-demand” value for hover/any-hover media queries has been removed from the spec about a year ago because it doesn’t have a convincing use case. Moreover, mobile Safari doesn’t support this specific value for hover/any-hover queries.
