Webgl blend func tests

<!-- Please describe your changes on the following line: -->
Add a function that validates the conditions for [Constant Color Blend](https://www.khronos.org/registry/webgl/specs/latest/1.0/#CONSTANT_COLOR_BLEND) in the WebGL specs. ./mach run -r tests/wpt/web-platform-tests/webgl/conformance-1.0.3/conformance/misc/webgl-specific.html

<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: -->
- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [ ] These changes fix #__ (github issue number if applicable).

<!-- Either: -->
- [x] There are tests for these changes OR
- [ ] These changes do not require tests because _____

<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->
