Dawn: Promote DisallowUnsafeAPIs as instance toggle

This CL add Instance and Adapter toggle stage, and promote
DisallowUnsafeAPIs as an instance toggle, and can be required using
DawnTogglesDescriptor chained in instance descriptor when creating
instance. The instance's toggles state will get inherited to adapters
and devices it create. Related tests are implemented and updated.

Toggles inheritance can be overriden if not forced, so requiring
DisallowUnsafeAPIs when creating device is still available and working
like before.

Note that currently we don't have toggle of adapter stage, and can not
require toggles when creating adapter, until follow up CLs implement it.
Currently the toggles state of a adapter is simply inherited from
instance.

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.
