Change for "Allow GPUTexture where GPUTextureView is used"?

[kainino0x]

Issue corresponding to upstream spec change gpuweb/gpuweb#5228
Which is just an ergonomic improvement.

We did not make any change to webgpu.h for this change. I'm just filing this issue to document why Dawn didn't propose any change.

The C struct is:

typedef struct WGPUBindGroupEntry {
    WGPUChainedStruct * nextInChain;
    uint32_t binding;
    WGPU_NULLABLE WGPUBuffer buffer;
    uint64_t offset;
    uint64_t size;
    WGPU_NULLABLE WGPUSampler sampler;
    WGPU_NULLABLE WGPUTextureView textureView;
} WGPUBindGroupEntry WGPU_STRUCTURE_ATTRIBUTE;

We can't edit this because it's stable. So we would need to add an extension struct like:

// chained in WGPUBindGroupEntry
typedef struct WGPUTextureBindingEntry {
    WGPUChainedStruct chain;
    WGPUTexture texture;
} WGPUTextureBindingEntry WGPU_STRUCTURE_ATTRIBUTE;

However this is unergonomic and defeats the purpose of the ergonomic improvement. It's much easier to just type .CreateView().

So there is no point in adding anything to webgpu.h.
