Suppress perf tests on Mac/Intel

Suppresses UniformBufferUpdatePerf on Mac/Intel when running multiple
uniform buffers at full upload size. This combination of hardware and
parameters flakily results in a pure virtual function being called,
which then causes the entire task to fail.

This practically only occurs on the AMD Macbooks when using their
integrated GPUs, but there is currently no way to differentiate those
from the Mac Minis with Intel GPUs that are not running into this.

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.
