Enforce FCM settings via the blacklist rather than in-code version checks.

As of http://crrev.com/228816 both Win and Mac bots are properly using the blacklist and version checks in compositor_util.cc are no longer required.

Also cleanup the blacklist to:
1) Put Vista and XP blacklisting of FCM under the same rule.
2) Always blacklist Stage3D when FCM is disabled (as in https://codereview.chromium.org/25602002).

This is part of https://codereview.chromium.org/22198004/ which was split out into smaller chunks (now a follow-up to https://codereview.chromium.org/23703017/).
