fix supports_device() in python interface

[fs-eire]

Description

get_device() returns a string of hyphen connected device names, such as "GPU-DML". It's a problem that when CUDA is disabled but OpenVino GPU is enabled in the build, because in this case get_device() returns "CPU-OPENVINO_GPU", so supports_device("CUDA") will return True in this build.

Splitting the value of get_device() by "-" and check if the input is in the list is not an option because it seems some code in the code base stores the value of get_device() and use the value to call supports_device(). Using this implementation will cause supports_device("GPU-DML") to return False for a build with get_device() == "GPU-DML" because "GPU-DML" in ["GPU", "DML"] is False.

This change also helps to avoid further problems when "WebGPU" is introduced.
