Add "GenerationInUse" and "GenerationSupported" to PCIeDevice interface

Add PCIeDevice properties "GenerationInUse" and "GenerationSupported"
then let managerment APIs like redfish can expose the information.

New property:
GenerationInUse    : The PCIe interface generation in use by the device
GenerationSupported: The maximum PCIe generation supported by the device

Dbus Sample output:
