This is temporary until GPUSamplers are added in the next big patch.

I'm no longer calling destroy() in the destructor here as it would expose when garbage collection happens.

It would be nice if you could provide a description of what this patch actually does.

> Source/WebCore/Modules/webgpu/GPUBindGroupLayoutBinding.h:31
> +#include <wtf/OptionSet.h>

I don't think you need this.

> Source/WebCore/Modules/webgpu/GPUBindGroupLayoutBinding.h:46
> +    GPUShaderStageFlags visibility;

Shouldn't this be GPUShaderStageBit::Flags?

This could all go on one line.

Not sure this will compile in Release configuration.

I would prefer to put the conditional in here, and an ASSERT in the endBlitEncoding.

if (m_blitEncoder)
  endBlitEncoding();

> Source/WebCore/platform/graphics/gpu/cocoa/GPUCommandBufferMetal.mm:91
> +    if (!m_blitEncoder)
> +        return;

And here would just be ASSERT(m_blitEncoder), unless you call it from other places.

The IDL calls for an unsigned int and bindings doesn't know how to convert, even though it's not a strongly-typed enum.

Correct, this function is also called by GPUQueue::submit(), which doesn't need to know whether the command buffer actually has an active blit encoder or not.
