Corentin Wallez e10e6b0db8 Vulkan: Fix layout of Sampled+ROStorage texture.
Vulkan requires that storage images be in the GENERAL layout, and requires
that we choose a layout at VkDescriptorSet creation. This means that
since Sampled+ROStorage texture may sometimes be used as both usages in
the same pass, they must always be in the GENERAL layout even for
SampledTexture bindings.

Fix this by looking at the texture's creation usage in VulkanImageLayout
for wgpu::TextureUsage::Sampled.

Also add a regression test that triggers a Vulkan Validation Layer error
without this fix.

Bug: dawn:635

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 on Windows 10
    • Metal on macOS and iOS
    • Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
    • OpenGL as best effort where available
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
