Add MatMul with 2-dimensional shared array shader

The previous matmul is using 1-dimensional shared array. This PR
adds the 2-dimensional shared array. The perf result shows that:
1. For 1-dimensional shared array, enabe-robustness wil bring almost 2x
regression both for matmulFloat and matmulVec4 on Intel CFL.
2. For 2-dimensional shared array, enabe-robustness will bring almost 2x
regression on matmulFloat. But have little impact on matmulVec4 on Intel
CFL.

Tested on Intel_R_UHD_Graphics_630.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the work-in-progress 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 on Windows 10
    • Metal on macOS and iOS
    • Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
    • OpenGL as best effort where available
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
