Feature Request: create SyclDevice and attribute to and from dlpack Enum in Python

[icfaust]

There is already functionality for converting SyclDevices into dlpack_device Enums (c_dlpack.get_parent_device_ordinal_id) occurring in Cython. dpctl Tensors also already include a __dlpack_device__, would it be possible to enhance operability with dlpack by including a __dlpack_device__ attribute to SyclDevice, and make a SyclDevice creator arg if passed a dlpack enum?

Thanks
