Allow readwrite storage texture in pipelinelayout matches writeonly in shader

This patch enables using read-write storage texture access in pipeline layout
and declaring the correspondent storage texture as write-only in shader.

Note that currently we still disallow read-write access in pipeline layout be
compatible with read-only in shader as on D3D12 read-write access in pipeline
layout will be implemented with an UAV, while read-only access in shader will
consume an SRV slot.

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.
