servo: Merge #13208 - Fix WebGL tests & Implement WebGLRenderingContext::{validateProgram, getProgramInfoLog, disableVertexAttribArray} (from MortimerGoro:programinfolog); r=emilio
<!-- Please describe your changes on the following line: --> Implement WebGLRenderingContext::{validateProgram, getProgramInfoLog} and improve WebGL testcase to show shader link and validation errors. --- <!-- 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 - [X] These changes fix #13199 (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. --> Source-Repo: https://github.com/servo/servo Source-Revision: fc251384a76547167c027d69c28deae8c410c626
