MiraclePtr: Revert PipelineLayout::constants rewrite.

The "Mac FYI ASAN (Intel)" bot is detecting this is assigned a dangling
pointer.

See:
https://source.chromium.org/chromium/chromium/src/+/main:base/memory/raw_ptr_asan_service.cc;l=354?q=%22This%20crash%20occurred%20due%20to%20an%20attempt%20to%20assign%20a%20dangling%20pointer%20t%22

It needs to be investigated.

In the meantime, this patches revert this part of the rewrite to
unblock the CI.

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.
