Restore more webkit-font-smoothing.

Restore more webkit-font-smoothing.

With https://codereview.chromium.org/175253002 (Blink r182920)
webkit-font-smoothing was broken on Mac.

Blink 185065 restored webkit-font-smoothing when using
non-subpixel-smoothed text, but did not fuly restore the
previous behavior.

This change should fully restore the previous behavior.

The failing tests are all virtual/antialiased/ pixel tests which use
'-webkit-font-smoothing: none' in order to force that property. These are
actually good tests, in that they test if this property is working or not. I
believe they should simply be rebaselined. I will create a patch for that.
