Use CSS3 style matching on Android.

Android framework doesn't really use this, the largest user is Chromium.
At the moment this doesn't resolve oblique requests in a nice way, but
the existing code is somewhat close to CSS3 rules already. Instead of
adding oblique handling manually, just use the existing CSS3 style
matching.
