[dawn][metal] ArgBufs: fix type of dynamic offsets buffer

Dynamic offsets are originally u32 (per JS and C specs). For some
reason, we convert them to u64 internally (like other buffer offsets).
But it's easier to deal with them as u32 when emitting MSL, so convert
them back to u32 before setBytes.

Test: BindGroupTests.DynamicOffsetOrder
Bug: 363031535

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the 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.
