Reapply "Use SearchPaths to load DX compiler DLLs"

This reverts commit 80062b708e44aa4d8c48e555ed0cc801396069f6.

It was reverted because EGL tests were failing on the Dawn -> Chromium
roll.  Those should now be fixed via "Fix EGLImage test failures"

>     Use SearchPaths to load DX compiler DLLs
>
>     Previously, DX compiler DLLs were loaded using LoadLibrary with no path.
>     For better security, load DX compiler DLLs using full paths, with
>     SEARCH_DLL_LOAD_DIR | SEARCH_DEFAULT_DIRS.
>
>     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 employs the search
>     path.

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.
