Remove ConcurrentTransformedShaderModuleCache

ConcurrentTransformedShaderModuleCache held both compiled SPIR-V and
VkShaderModule. There is already caching of SPIR-V in BlobCache. The
transformation from SPIR-V to VkShaderModule is inexpensive. This extra
layer of caching isn't really necessary so remove it.

Render/compute pipeline now call vkDestroyShaderModule() after
compilation is complete. This also removes the need for FencedDeleter to
handle that.

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.
