D3D11: Cache shader objects from same shader blobs.

Currently, Dawn only caches the shader *blob* (the compiled HLSL
bytecode) but not the actual D3D11 shader *objects*
(ID3D11VertexShader, ID3D11PixelShader, ID3D11ComputeShader). The
creation of these shader objects from the blob can be a non-trivial
operation, impacting performance.

This change introduces caching for the D3D11 shader objects themselves.
The caching mechanism uses the SHA3 hash of the shader blob as the key
to store and retrieve the D3D11 shader objects. This allows for reuse
when multiple pipelines use the same underlying shader blob, thereby
reducing redundant object creation and improving performance.

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.
