Make bootstrap handle linux setup, include gstreamer, make bootstrap run standalone
Previously `./mach bootstrap` wasn't very useful on Linux, it would just install salt. This PR moves that to `./mach bootstrap-salt`, and has `./mach bootstrap` perform the installation steps mentioned in the README.
With these changes `./mach bootstrap` is a valid way of setting up the servo build. Additionally, this adds gstreamer setup to this for cases where gstreamer is not up to date.
Edit: And now, mach bootstrap is able to be run on a fresh system with just python installed (no need for virtualenv or libffi).

This disables bindgen's `logging` feature, which builds `env_logger`
with default features, including regex support. Disabling it allows
Gecko to build `env_logger` without the `regex` crate, reducing code
size.

Add WebGL conformance 2.0.0 tests
<!-- Please describe your changes on the following line: -->
This PR includes WebGL conformance 2.0.0 tests. For now I have disabled three folders in the new suite:
- `Conformance`: Tests WebGL 1.0 API like the current 1.0.3 suite we are using, but it includes a lot more tests and many expectations have to be updated. This is better to do in a separate PR because it will require to update github intermittent paths again and maybe detect new intermittents.
- `Conformance2\textures`: It causes a lot of timeouts because of using videos, svgs, and other complicated formats.
- `deqp`: It's a extra GPU testing suite included in the Khronos 2.0.0 suite. Disabled for now because it causes some timeouts.
So in a nutshell, it uses part of the 2.0.0 suite to test webgl 2.0 and keeps using 1.0.3 in order to test WebGL 1.0. It's good enough to enable TDD for the new WebGL 2.0 features
We can create follow-up issues for the next steps:
* deprecate 1.0.3 and use the new 'conformance' folder in 2.0.0 in order to test WebGL 1.0
* Enable `conformance2/textures` and 'deqp' tests once WebGL 2.0 implementation is more advanced or the timeouts are monitored in more detail.
