mshyperv: Introduce hv_numa_node_to_pxm_info()
Factor out logic for converting numa node to hv_proximity_domain_info
into a helper function.
Change hv_proximity_domain_info to a struct to improve readability.
While at it, rename hv_add_logical_processor_* structs to the correct
hv_input_/hv_output_ prefix, and remove the flags field which is not
present in the ABI.
