D3D12: Add a toggle to use DXC for HLSL compilation

This patch adds the following:
 - UseDXC toggle
 - Loads DXC (and DXIL to sign the DXBC) in d3d12/PlatformFunctions
 - Adds GetModuleDirectory to SystemUtils

GetModuleDirectory was added to prevent loading issues regarding dynamic libraries when the executable is not in the same path as the dawn module.

This patch doesn't add DXC to RenderPipelineD3D12 nor ComputePipelineD3D12.

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 on Windows 10
    • Metal on macOS and iOS
    • Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
    • OpenGL as best effort where available
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
