Rendering Ahem with antialiasing causes reftests to fail. Since it seems difficult to fix all the tests to prevent this we either need to ensure that Ahem isn't antialiased or turn off antialiasing entirely, which may make more tests work at the expense of test behaviour being less like shipped behaviour.

Add a pref called gfx.font_rendering.no_antialias_ahem which disables
antialiasing for any font with the family name "Ahem". This is useful
for wpt reftests where antialaising of Ahem causes spurious failures.

Depends on D7199
