  [WebGPU] dynamic bind group indices continue to be incorrect

Reviewed by Tadeu Zagallo.

The copy in PipelineLayout assumed the bind group
indices were linearly increasing but this was not guaranteed as
they were stored in a HashMap.

Build a shadow sorted container to address this as the data does
not change after creation.

* Source/WebGPU/WebGPU/BindGroupLayout.h:
* Source/WebGPU/WebGPU/BindGroupLayout.mm:
(WebGPU::Device::createBindGroupLayout):
This was being sorted uncessarily each iteration, correct this.
