[M123] D3D12: Workaround textureDimensions issue with SM6.6 on Intel Gen9/Gen11

textureDimensions() produces incorrect results with SM 6.6 on Intel D3D
driver 27.20.100.9664 on Intel Gen9/Gen11 GPUs, but works well on
drivers > 27.20.100.8935 and < 27.20.100.9684, or using SM 6.5.

The version 9664 is OEM driver, and not sure there is any other OEM
drivers between 8935 and 9684, so use SM 6.5 in the driver version
range as a workaround on Gen9/Gen11 GPUs.

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.
