Revert "[Win] Call CompareObjectHandles directly"

This reverts commit 80906a48e38c4d549764f8159645c340e9c6844f.

Reason for revert: this is breaking the roll into Chromium with this linker error:

lld-link: error: could not open 'onecore_apiset.lib': No such file or directory

Example failing roll:
https://chromium-review.googlesource.com/c/chromium/src/+/6681536

Original change's description:
> [Win] Call CompareObjectHandles directly
>
> Now that Chromium only supports Win10+, we can call
> CompareObjectHandles directly. No need to query for its function
> pointer, or manually keep kernelbase.dll alive.

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.
