Force other forced color properties at used value time

Forced colors should now happen at used value time. This change adjusts
the used value of text-decoration-color, -internal-visited-text-
decoration-color, column-rule-color, -internal-visited-column-rule-color,
-webkit-tap-highlight-color, -webkit-text-emphasis-color, and -internal-
visited-text-emphasis-color to take forced colors into account. No
internal properties were needed since we only ever force these set of
properties to currentColor in forced colors mode.

The only remaining property to move to used value time is 'color'.
