Add getRectCount to SkRegtion
It is useful to know how many rects comprise a region,
since in some situations we can optimize code based on
the complexity of the region. For instance, if we use
SkRegion for tracking invalidation we might opt to use
the region bounds as invalidation instead of iterating
over each rect.
