Add missing WebGPU limits to Constants.h

This will help check that the Vulkan devices are enough for WebGPU in
a following CL.

In addition to additional limits this CL:

 - Change maxColorAttachments 4 -> 8 to match WebGPU
 - Renames kMinDynamicBufferOffsetAlignment to
   kMinUniformBufferOffsetAlignment.
 - Renames kMaxVertexBufferStride to kMaxVertexBufferArrayStride.
 - Changes validation of buffer offsets to use the separate uniform and
   storage limits (but no test is added because they are the same).
 - Adds validation and a test for kMaxStorageBufferBindingSize.
 - Augment the null::Device memory limit for that new test (it allocates
   a buffer of 512MB).
 - Fix the maxColorAttachment test to not use hardcoded values.

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
