Andrei Volykhin 65620b623d webgpu: Add the latest spec compliant GPUAdapterInfo (#39960) ...

According to the WebGPU specification there are some missing readonly
attributes (subgroupMinSize, subgroupMaxSize, isFallbackAdapter) for
GPUAdapterInfo IDL interface.

See https://gpuweb.github.io/gpuweb/#gpuadapterinfo

Added the new readonly attributes:
- GPUAdapter 'info' attribute
  https://gpuweb.github.io/gpuweb/#dom-gpuadapter-info
- GPUDevice 'adapterInfo' attribute
  https://gpuweb.github.io/gpuweb/#dom-gpudevice-adapterinfo

Removed marked as the deprecated the following method and attribute from
GPUAdapter interface:
- 'requestAdapterInfo' method
- 'isFallbackAdapter' attribute

Testing: Improvements in WebGPU CTS expectations
