Fix cull nesting assertion.
Cull rects are in local coordinates and cannot be compared directly.
No wonder it was so hard enforcing this in Blink :o
This moves the validation logic into SkCanvas, using a device-space
cull stack (debug build only).
There are still some Blink bugs causing violations, so for now I'd like
to keep this as an error message only.
