[Impeller] Include CPU blends + Flutter blend reference image in goldens (#43117)

Part of https://github.com/flutter/flutter/issues/128606.

- Adds blend imagery that matches the Flutter BlendMode documentation:
https://api.flutter.dev/flutter/dart-ui/BlendMode.html
- Adds a clear side-by-side comparison of SaveLayer blending vs CPU
blending to make verifying correctness possible.
  - Top squares are SaveLayer-applied blends.
  - Bottom squares are CPU blends.
