Update Dawn GN builders to use shared GPU helpers

Updates almost all Dawn GN CI and try builders to use the shared GPU
helpers from chromium-luci instead of essential redefining them. The
only occurrence not migrated is the presubmit builder since there is not
currently an appriate helper for this.

This is largely a functional no-op with most changes just adjusting
dimensions to be in sync. The one exception to this is for Windows
builders, which now prefer machines with SSDs. The majority of our CI
and try Windows GCE capacity has SSDs at this point, so this should be
fine.

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.
