Auto merge of #25637 - szeged:wgpu_crete_bind_group, r=jdm

Initial implementation of GPUBindGroup for WebGPU

Added WebIDL bindings for `GPUBindGroup`.
Implemented the `createBindGroup` function of `GPUDevice`
Renamed `GPUBindGroupBinding` to `GPUBindGroupBindings` and `GPUBufferBinding` to `GPUBufferBindings` in the WebIDL, because these names are already occupied.
