Introduce mshv_debugfs_counters.c, containing static data corresponding to HV_*_COUNTER enums in the hypervisor source. Defining the enum members as an array instead makes more sense, since it will be iterated over to print counter information to debugfs.
Include hypervisor, logical processor, partition, and virtual processor counters.
