Disable render passes on Windows until support can be detected

Per https://microsoft.github.io/DirectX-Specs/d3d/RenderPasses.html#checking-for-support,
render passes on Windows originally shipped in an incomplete form
that drivers could not take advantage of. The feature has been
repaired now but to detect whether you're getting the fixed version,
you need to query for the D3D12_FEATURE_DATA_D3D12_OPTIONS18
structure and check the RenderPassesValid field inside.

Until we upgrade Dawn to use a version of the header file with the
structure, we force render passes to be disabled. See
https://issues.chromium.org/issues/348202695 for additional information.

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.
