Reland "Reland "Improve DX compiler library loading"" This is a reland of commit e579b628e5d5276086b6a2eaefa1718586bc7e18 Add dawn_force_system_component_load for projects (like Skia) which require that Dawn load all compiler DLL from System32. Best security is to leave the default value which (now) loads compiler DLLs from the same directory as Dawn code. On Chromium builds (such as x86) which do not build DXC, place the DLLs from the SDK into the build folder to appease infra tools that copy the DLLs unconditionally. Improve DAWN_USE_BUILT_DXC to use the #define to skip loading the DLLs altogether.

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:
