This reverts commit 382f3853.

Reason for revert: crbug.com/895592

Original change's description:
> Add Dawn, SPIRV-Cross and GLFW to //third_party
> 
> Dawn is a library implementing WebGPU in native. It uses SPIRV-Cross to
> translate shaders from SPIRV to other shading languages, and requires
> glfw for testing.
> 
> Adds the Zlib license to the list of allowed license for Android.
> 
> This also adds back shaderc that was very recently removed. So hopefully
> a new third_party review isn't required.
