WebGPU backend error: Binding size is smaller than the minimum binding size

[yyc-git]

Hello everyone, Thanks for your great work!

relate to #229 , but this time I use webgpu backend

Now when I use input with 256*258 or 1280*720 size image and inference, it all error with the same error info:

Binding size (68) is smaller than the minimum binding size (72).
 - While validating entries[5] as a Buffer.
Expected entry layout: { binding: 5, visibility: ShaderStage::Compute, buffer: { type: BufferBindingType::Uniform, hasDynamicOffset: 0, minBindingSize: 72 } }
 - While validating [BindGroupDescriptor] against [BindGroupLayout]
 - While calling [Device].CreateBindGroup([BindGroupDescriptor]).

[Invalid BindGroup] is invalid.
 - While encoding [ComputePassEncoder].SetBindGroup(0, [Invalid BindGroup], 0, ...).

[Invalid CommandBuffer] is invalid.

this time I use webgpu backend

Sorry, current WebNN Polyfill API doesn't support WebGPU backend, we will support later.
