Dawn: vertex buffer never OOB with zero stride count draw/Indexed

According to the spec, when call draw or drawIndexed, vertex step mode
vertex buffer never OOB if (vertexCount + firstVertex) = 0, and instance
step mode vertex buffer never OOB if (instanceCount + firstInstance) = 0.
Modify the validation implementation to be aligned with the spec, and
add corresponding unit tests.
This patch also add unit test case for (strideCount - 1) * arrayStride +
lastStride <= bound buffer size < strideCount * arrayStride.

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
  • Tint is a compiler for the WebGPU Shader Language (WGSL).
