[dawn][vk] Fix uses of pipeline robustness when robustness is disabled.

When Dawn's robustness is disabled we use pipeline robustness to tell
the driver to not do any robustness if it can, so we still need to
enable the Vulkan extension in that case, to allow passing
VK_PIPELINE_ROBUSTNESS_BUFFER_BEHAVIOR_DISABLED_EXT.

When robustness is disabled we also need to skip setting the
VulkanUse*RobustAccess2 toggles since the relevant features are not
enabled, which would cause a VVL error when they make pipeline
robustness request "robust access 2".

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.
