ShaderModuleVk: Add a renamer to make other transforms safe.

Without this other Tint transforms may end up calling user code instead
of builtins (for example for the min() used in robustness).

This commit does the following changes:
 - Changes ShaderModuleVk to return a CompiledSpirv object instead of
   just a Spirv Blob so that a remappedEntryPoint can be stored in the
   cache alongside the SPIR-V.
 - Inlines the logic and simplifies TransformedConcurrentShaderModuleCache
   slightly (by introducing a struct instead of std::pair, and adding a
   conversion method to ModuleAndSpirv).
 - Adds the Renamer transform to ShaderModuleVk and adapt the code to
   use the remappedEntryPoint where needed (pipeline creation and
   post-compilation reflection).
 - Adds a test where the min() used by the robustness transform is
   overriden to return a constant 0.
 - Moves the Renamer transform to be just after the SingleEntryPoint
   transform in D3D12 and Metal as well so as to make the test pass.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the work-in-progress 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.
