Brandon DeRosier 320a689d5e [Impeller] Add tests for foreground blends with mask blurs (flutter/engine#42687) ...

Part of https://github.com/flutter/flutter/issues/127232.

Both of these tests should be rendering as a clipped and blurred green circle. Making mask blurs interact correctly with color filters is not going to be trivial... These bugs extend beyond the filter graph itself. Want to get some goldens in to compare against.
