D3D11: Add an option to skip fence signal when accessing a STM.

Add a new option to SharedTextureMemoryD3D11Texture2DDescriptor to skip
fence signaling when STM's texture is accessed in a command buffer.

This would typically be used when the texture is shared between ANGLE &
Dawn which share the same D3D11 device. Thus no fence is needed.
It will also be useful for dcomp textures. Dcomp doesn't use the same
D3D11 device as Dawn. However it's not required to signal any fence
before returning the texture to dcomp. Dcomp still requires dawn to wait
on its own fence anw.

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.
