Upgrade the version of go used in CI

The slices package was added in Go 1.21, but CI scripts tried to use 1.18. This switched to 1.23 because only the 2 most recent major Go releases are supported officially.

PS: I know, there are other issues in the CI, one is just about [fixing `fetch_dawn_dependencies.py`](https://github.com/google/dawn/compare/main...eliemichel:dawn-prebuilt:eliemichel/fix-fetch-deps) but then we still have undefined symbols in macOS build:

```
ld: Undefined symbols:
  tint::ast::transform::SubstituteOverride::Config::Config(tint::ast::transform::SubstituteOverride::Config const&), referenced from:
      tint::ast::transform::SubstituteOverride::Config* std::__1::construct_at[abi:v160006]<tint::ast::transform::SubstituteOverride::Config, tint::ast::transform::SubstituteOverride::Config, tint::ast::transform::SubstituteOverride::Config*>(tint::ast::transform::SubstituteOverride::Config*, tint::ast::transform::SubstituteOverride::Config&&) in ShaderModuleMTL.mm.o

Should I share fixes one at a time or rather try and pack everything into the same commit?

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.

Dawn provides several WebGPU building blocks:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A “native” implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
