Corentin Wallez 1249ada986 Vulkan: Load promoted extensions or core entrypoint as needed 
Previously we would always assume that if the driver supported a Vulkan
version it would also support extensions that were promoted in that
version. This is not a spec requirement, so instead try to load the core
entrypoints, and only if the version is not available, load the
extension entrypoints.

Also renames VulkanFunction members that are from promoted extension to
not have a vendor prefix.

Also tag the promoted extensions that are the same in a core version as
available when that core version is available. This simplifies checking
for features in the Vulkan backend.

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
