PerfTest: Add a workgroup impl and enable D3D subgroups for Mat-Vec Mul test

This CL add a new shader implementation for matrix-vector multiply perf
test which split the input vector and matrix into blocks for invocations
within a workgroup and at the end use workgroup memory to add up the
result. This implementation has comparable or better performance than
the subgroups implementation on tested devices.
This CL also remove the suppression for subgroups on D3D12 device.

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.
