Impl copyTexImage2D and copyTexSubImage2D

- [X] `./mach build` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [x] There are tests for these changes

Implement copyTexImage2D and copyTexSubImage2D for WebGLRenderingContext. Feedback would be appreciated. I did my best to follow the [spec](https://www.khronos.org/registry/webgl/specs/latest/1.0/#5.14.8). Please let me know if I missed anything. I couldn't find tests for this. Let me know if I should create one. I'm more than happy to do so. As always any feedback, comments,or critiques are very welcome 😄
