D3D11: Reuse implicit pixel local storage attachments when possible

This patch supports reusing implicit pixel local storage attachments
instead of always recreating temporary textures as implicit pixel
local storage attachments.

Note that currently on D3D11 backend we cannot create a Texture2D
UAV on a 2D array texture with baseArrayLayer > 0, so we have to
create one 2D texture for each implicit pixel local storage slot
instead of a 2D array texture with 4 layers for all implicit pixel
local storage slots.

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.
