Metal: Detect validation layer via env variable.

There is a bug in AMD driver when pipelines are compiled in parallel
when validation layer is enabled. We already have a workaround for
in crbug.com/dawn/1200

However, the workaround only detects if the backend validation is
explicitly enabled by users. There are cases when the validaton layer
is enabled eternally (via Xcode or commandline, etc). This CL attempts
to detect those cases by checking METAL_DEVICE_WRAPPER_TYPE &
MTL_DEBUG_LAYER environment variables.

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, 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.
