<!-- Please describe your changes on the following line: -->
Fix interface exposure per [the specs](https://html.spec.whatwg.org/multipage/scripting.html#2dcontext).
One lingering question I have is if [`CanvasPath`](https://html.spec.whatwg.org/multipage/scripting.html#canvaspath) needs to be added to `interfaces.worker.js` since it *is* exposed to the `Worker` environment. I tried adding it to the `interfaces.worker.js` list but it failed tests at https://github.com/servo/servo/blob/master/tests/wpt/mozilla/tests/mozilla/interfaces.js#L82

This might be a bad idea, especially on the webidl side. However, we started talking about the idea that modelines are a lint error (https://github.com/servo/servo/issues/10719), and these changes would be required before enabling a modeline lint.
If it bitrots, it's easy to recreate with
```
find * -type f -exec sed '/- Mode:/d' -i {} +
find * -type f -exec sed '/ vim:/d' -i {} +
git checkout -- python/tidy/servo_tidy/tidy.py
git checkout -- python/tidy/servo_tidy_tests/spec.webidl
git commit -a

Confirmed that dumping the output of toDataUrl on toDataURL.png.primarycolours.html gives the same results as Firefox (including padding)

I couldn't add the `getContextAttributes` method since `CodegenRust`
doesn't know how to return a dictionary value, I'll take a look at it ASAP.
I think the helper functions can return directly the renderer, since they're used just for that, but I wanted to hear your opinions about this.
By the way I'm interested in adding more serious tests for WebGL, and I think the [khronos conformance suit](https://github.com/KhronosGroup/WebGL/tree/master/conformance-suites/1.0.3) should be the best option.
Should I try to integrate it in wpt, or making a `tests/webgl` directory (or similar) inside the servo tree? (Maybe this question should be for @Ms2ger)

GitHub doesn't allow me to reopen#5769, so I created this.
Sorry about the merge fail, my bad :/

This PR uses customized GL context creation code, right now only working under Linux, so I expect the clearcolor test to fail on other platforms.
It addresses some other problems:
* Propagates context creation error to the top, returning null if not found.
* Uses GLContextAttributes, which will allow us to write WebGLContextAttributes easily.
* Doesn't allow a 2d context and a WebGL context coexist.
* Panics when resizing the context to larger dimensions (to be fixed soon, but better than blindly allowing it).
Removes some unused dependencies

@jdm @ecoal95 I'm working on making VR happen in the Browser and I want to bring to Servo the [webVR APIs](https://github.com/MozVR/webvr-spec/blob/master/webvr.idl) we already have in Gecko. Before anything happens we need a working implementation of WebGL (and also the [fullscreen API](https://fullscreen.spec.whatwg.org/)). My implementation is very basic and probably naive (I just recently started to contribute to Servo). My patch is just a starting point:
- It only implements ```clearColor``` and ```clear``` methods of the [WebGL spec](https://www.khronos.org/registry/webgl/specs/latest/).
- It uses the readback strategy that ```canvasRenderingContext2D``` is using (The webgl task paints stuff independently on it's own buffer and the compositor task request the pixels back to the webgl task when it needs them) I'm sure there are much better ways to handle this. Latency and FPS are critical in VR so we have to figure out the fastest way to push pixels to the screen. I've read something about layerizing the canvas but I'm still not sure what that even means :)
- There's an included test you can try ```./mach run tests/ref/webgl-context/clearcolor.html```
@ecoal95 I know you'll be working on this for the next three months. With a foundation in place we will be able to make quick progress in parallel. This is exciting!
