[dawn] Make ComboLimits chain only standard limits extensions by default

Some experimental limit extensions are currently output-only
(DawnTexelCopyBufferRowAlignmentLimits and DawnHostMappedPointerLimits
are ignored in requiredLimits, and operations are not validated against
them). Remove these experimental extensions from ComboLimits to stop
warning span about that problem. This also obsoletes the #ifdef
__EMSCRIPTEN__ that I used previously to make this work on Wasm.

Instead, callers can pass any additional extensions to GetLinked() as
variadic type-inferred arguments. Two tests are updated to use this.

Also revert 2987f3c04d9b4f401dbe4fac6a52832ff90f17aa
"[dawn][wasm] Fixes WASM builds by excluding native utils."
since that should no longer be necessary.

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.
