Make SetViewport validation match upstream WebGPU.

As a side-effect this allows empty viewports which need special handling
in Vulkan because it is not allowed to set width to 0 (but ok to set
height to 0).

Validation tests are updated to cover the new validation checks.

Most of the viewport end2end tests are rewritten because they didn't
pass the new validation.

A new end2end test is added to test various kinds of empty viewports to
cover the extra logic 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
