Zhaoming Jiang 7ca82ac4d0 dawn: Refactor device creation and add shader-f16 feature
This CL modifies the way adapter creating devices, adds `shader-f16`
feature, and deprecates the `dawn-shader-float16` feature which is no
longer used.
Details:
1. Parse the toggles chained with device descriptor in
`adapter::CreateDeviceInternal`, which are then used to validate
features requirement within `CreateDeviceInternal` and passed to device
constructor as initializer.
2. When creating device, validate features requirement in
`CreateDeviceInternal` with toggles known, make sure to fail the device
creation if a required feature is not supported by adapter or is guarded
by certain toggles which were not enabled/disabled. Feature ShaderF16
and ChromiumExperimentalDp4a are validated in this way. Unittest is
added to check creating devices with toggles-guarded features required.
3. Add `shader-f16` feature, which allow `using f16;` in WGSL code.
End-to-end tests are added to test a trival f16 WGSL shader could be
used if and only if the device has `shader-f16` feature.
4. Deprecate the `dawn-shader-float16` feature, which will be completely
removed after cleaning up Blink code.

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, 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.
