Revert "Support validating buffer usage with usage validation mode"

This reverts commit 1f3f5df6810adfd8c37ce25fb3c22c92a4e9bf02.

Reason for revert: blocks rolling into Chromium
https://chromium-review.googlesource.com/c/chromium/src/+/5841338
https://ci.chromium.org/ui/p/chromium/builders/try/dawn-mac-arm64-deps-rel/8457/overview
[ RUN      ] InternalStorageBufferBindingTests.QueryResolveBufferBoundAsInternalStorageBuffer/Metal_Apple_M2
Error: Assertion failure at ../../third_party/dawn/src/dawn/native/CommandEncoder.cpp:1128 (BeginComputePass): device->IsLockedByCurrentThreadIfNeeded()

Original change's description:
> Support validating buffer usage with usage validation mode
>
> This patch adds `UsageValidationMode` as the third parameter of
> `ValidateCanUseAs` with a buffer as input to align with the
> format of the function `ValidateCanUseAs` with a texture as input.
>
> This patch also updates the test `InternalStorageBufferBindingTests`
> by using classes in `native::` instead of the `wgpu::` to better
> test the `internal usage` of the buffers.
>

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.
