Loko Kung 79f62081c0 Fixes bad mem-read in Vulkan's ~DescriptorSetAllocator.
Bug was a result of an external BGL reference that lingered after device was destroyed leading to a bad read on the device's FencedDeleter when the BGL reference was finally released. Fix just makes sure that the previous code path runs during the device destruction instead of afterwards.

- Removes passthrough call in BGL to the allocator and instead has the device keep track of the allocator directly so that the list can be used to both deallocate bind groups and bind group layouts at the end.
- Makes the allocator an ObjectBase so that we can have an explicit copy of the device since getting it from the layout can be dangerous now that the allocator may outlive the layout.

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
