Fix GrAARectRenderer's handling of unsorted nested rects

Fix GrAARectRenderer's handling of unsorted nested rects

What is going on here is that, after the mapPoints in fillAANestedRects, devInside was upside down so the isEmpty check was always firing. I don't see why we need to avoid having devInside sorted.

lgtm, too. But let's make sure we handle the winding fill/wound the same way
case correctly.

GrContext.cpp::is_nested_rects explicitly checks that the directions returned
from isNestedFillRects are opposite.
