Refactor ShaderModule initialization into a "task"

Refactor ShaderModule creation to have an Initialize function in the
front-end which does BlobCache logic and shader module parsing within a
lambda.

This task is currently executed immediately in-thread and validation
errors are stored in ShaderModuleBase. DeviceBase::CreateShaderModule always
returns a ShaderModule unless there was an internal backend error.

This task will be run asynchronously in the future.

Asynchronously adding errors to error scopes is not completed yet so
DeviceBase acquires all errors and consumes them immediately.

Refactored WGPU backend ShaderModule to not use the Initialize method.
Simply always create a shader module, don't try to optimize for
creating one only in the non-error case.

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.
