Print the full path for errors occurring in the servo crate
<!-- Please describe your changes on the following line: -->
`Cargo` will print the path where it runs.
Origin python script `cd` into the crate folder, so the root path is set in the crate.
Now I use `--manifest-path PATH` to `cargo build`, so the root path is at `servo`.
Origin path in error message:
```
error: expected one of `!` or `::`, found `#`
--> lib.rs:24:1
```
Now it would be:
```
error: expected one of `!` or `::`, found `use`
--> ports/geckolib/glue.rs:11:1
```

Check if the NDK version is 12
<!-- Please describe your changes on the following line: -->
Since we only support NDK 12(b), we should add some script to check for that.
User might download 15 or 16, and would get some errors.

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.
