D3D12: Always skip Robustness transform on non-DBO storage buffers

This patch adds all the storage buffers and read-only storage
buffers without Dynamic Buffer Offset to the 'ignore-list' of Tint
Robustness transform on D3D12 backend because currently in Dawn they
will always be bound to descriptor tables and translated into
ByteAddressBuffers, where D3D12 runtime can guarantee that
out-of-bounds-reading will always return 0 and out-of-bound-writing
will always take no action.

Note that currently we cannot skip robustness transform on uniform
buffers because in some situations FXC will report compilation error
when there is OOB access to the sized array declared in cBuffer.

This CL can improve about 11% of the performance of
dawn_perf_test.ShaderRobustnessPerf.

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.
