Support new format of IPv4 device path node, FibreEx and PcieRoot device path node in DevicepathDxe driver.

Meanwhile, unnecessary (UINTN) typecast is removed and a buffer truncating bug is fixed. The buffer truncating bug may cause DevicePathToText generates wrong text representation if a input device path is too long.
