Manually load CONDITION_VARIABLE methods on Windows, checking for failure (XP).
Tested by running DM on XP. Before this patch, it fails at startup (even just out/Debug/dm --help). Now it asserts for other reasons later on in user code, which is just fine by me.
The net effect is that SkTaskGroups will always be synchronous on XP. That's not ideal, but a step up from crashing.
