Support torch.accelerator.get_device_capability on XPU (#170747)

Browse Source 
# Motivation
This PR adds support for `torch.accelerator.get_device_capability` on XPU. At the current stage, it reports a limited set of basic scalar data types, taking potential software emulation into account where native hardware support may not be available.
