[Feature Request] Get device ids via get_available_device_ids()

[henryruhs]

Describe the feature request

I would like to have onnxruntime.get_available_device_ids() which returns a list of every device available.

This method might return either a List[str] or a Dict that contains the execution providers as keys. I assume that List[str] is good enough as you cannot install CUDA and ROCM for example at the same time, that being said: it will only return the ids of a single execution provider based what is installed.

from openvino import Core

Core().available_devices()

Describe scenario use case

I run a project that allows to pass the device_id via the CLI - at the moment I cannot validate the args, so this throws a Failed to parse provider option "device_id" on incorrect input.
