[native][d3d12] Create AgilitySDK DeviceFactory if Developer Mode

Developer Mode is required to use preview features from the Agility SDK,
such as LinAlg. Currently, if it's not enabled, we assert when creating
this factory.

Instead, if Developer Mode is not enabled, do not create the
ID3D12DeviceFactory used to later create the D3DDevice. We gracefully
fall back onto the normal D3DDevice so that the call to
CheckFeatureSupport for LinAlg fails and the SubgroupMatrix feature is
not enabled.

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.
