NVDIMMDeviceInfo, which inherits from PCDIMMDeviceInfo, is added to union type MemoryDeviceInfo to record information of NVDIMM devices. The NVDIMM-specific data is currently left empty and will be filled when necessary in the future. It also fixes "info memory-devices"/query-memory-devices which currently show nvdimm devices as dimm devices since object_dynamic_cast(obj, TYPE_PC_DIMM) happily cast nvdimm to TYPE_PC_DIMM which it's been inherited from.
