Vulkan: Correctly request 16bit shader features.

All the querying of extensions was correctly handled for the WebGPU
ShaderFloat16 extensions, except that we forgot to request it when
creating the VkDevice.

In practice this doesn't crash as most drivers won't check if the
extension is enabled, and just compile the shader code correctly.
However the Vulkan Validation Layers complain. This CL fixes it by
requesting the features on device creation.

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
