[M138] [dawn][native] Split maxImmediateSize into a separate limits group

Tiering is applied per group of limits such that if any of tier (n+1)
can't be supported, all limits go down to tier (n). maxImmediateSize
shouldn't be grouped with the OTHER limits because its tiers don't line
up with the others, causing maxVertexAttributes to be lowered
unnecessarily (it's the only limit in the OTHER group that varies from
tier0 to tier1).

Fixed: 430603273
Test: manually checked webgpureport.org in local windows chromium build
Bug: 430371785

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.
