Revert "fix buffer destroy"

This reverts commit 607ea6eecee8fee7f93e439c3eab6f87e763c938.

Reason for revert: Causes crashes because buffers are destroyed
too early. We can't make this change yet because emdawnwebgpu
doesn't have internal cross-references between objects (e.g.
from BindGroup or CommandBuffer, to Buffer) yet like Dawn does.

Original change's description:
> fix buffer destroy
>
> In native implementation, wgpuBufferRelease will trigger the buffer destroy (if refcount decreased to 0). But in emwgpu implementation, the buffer destroy won't happen.
>
> This change fixes the bug.

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.
