Austin Eng 96c4019214 Slab-allocate VkDescriptorSets 
This introduces a slab allocator for VkDescriptorSets which creates
a VkDescriptorPool pre-allocated with multiple VkDescriptorSets per
BindGroupLayout. In the future, we can deduplicate pools that have
the same, or roughly the same, descriptor counts.

This CL also removes the old DescriptorSetService and moves most of
the functionality onto the DescriptorSetAllocator itself to keep
the tracking logic in one place.

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
