Yunchao He 15fec68a4f Implement readonly depth/stencil attachment on Vulkan 
It requires to revise quite a few flags in order to implement
readonly depth/stencil attachment on Vulkan. For example:
  - VkAccessFlags,
  - VkPipelineStageFlags,
  - VkImageUsageFlags,
  - and the most important: VkImageLayout.

These revised flags need to be applied to many Vulkan objects.
For examples:
  - VkImageMemoryBarriers,
  - IMAGE_LAYOUT revisions in descriptor set (bindings),
    render pass, and subpass,
  - and loadOp/storeOp revisions in render pass and subpass.

This change also does some workarounds in order to make Vulkan
validation layers happy. For example:
  - use DEPTH_STENCIL_READ_ONLY image layout for binding a
    depth/stencil texture,
  - add DEPTH_STENCIL_ATTACHMENT_BIT image usage for binding a
    depth/stencil texture.

Note that STORE_OP_STORE is used for depth/stencil's storeOp for
readonly attachment. It leads to Vulkan validation error. This
change igores that error and let it proceeds and it works well.

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
