[d3d12] Fix end2end tests with Agility SDK

With Agility SDK enabled, SM 6.10 becomes available, which results in
some known DXIL issues in WARP, and enables features on certain bots
(Intel UHD 630) requiring updates of ArchTierLimits.

- Modify WorkgroupSizeUsesExplicitSubgroupSize test to iterate subgroup
  size up to subgroupMax / 2. This not only improves coverage, but
  allows us to test valid subgroup sizes on WARP (4) and skip the
  invalid ones.

- Suppress a number of copy tests that crash in WARP's ShaderJIT
  (crbug.com/563423066).

- Update ArchTierLimitsExhaustive for D3D12_Intel_R__UHD_Graphics_630
  (which gains TextureCompressionUnaligned) and Microsoft Basic Render
  Driver (_Integrated_GPU and _CPU) when Agility SDK is enabled.

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.
