Copy d3dcompiler_47 from WinSDK

Recently, Dawn was improved to load d3dcompiler_47 from absolute path
unless DAWN_FORCE_SYSTEM_COMPONENT_LOAD is false.

In GN builds, ANGLE places d3dcompiler_47.dll next to built
executables. Since no such placement code exists in Dawn nor ANGLE
for CMake, samples like HelloTriangle and ComputeBoids to fail to
load.

This CL refactors the CMake WinSDK detection code which copies
dxil.dll from the WinSDK to also copy d3dcompiler_47.dll from there
as well.

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.
