Apply mask layer transform when building wr mask layer
We should apply mask layer's transform or the position may be wrong. The mask layer's coordinate should be same as the masked layer. But for WebRenderXXXLayer, we already create a stacking context, so we need to deduct the offset of the stacking context.
A relative reftest is 'layout/reftests/w3c-css/submitted/shapes1/shape-outside-circle-033.html'. The mask layer's transform is not a identity matrix.
I also checked the reftest in bug 1354464. The tests are all passed with the patch.

Per try result, there is some unexpected-pass tests. I will remove the fails-if flag.  https://treeherder.mozilla.org/#/jobs?repo=try&revision=b01e30368286633cf349afed8a64932092c29585&selectedJob=94388585
