Add 4 APIs to DevicePathLib: ConvertDeviceNodeToText, ConvertDevicePathToText, ConvertTextToDeviceNode and ConvertTextToDevicePath.

Add a new instance of DevicePathLib which tries to locate the protocol and if it's not found, it uses the internal functions.

+#
+#  Device Path Library that layers on top of the UEFI 2.0 Device Path Protocol.
+#  If the DevicePathFromText/DevicePathToText protocol doesn't exist, the library
+#  uses its internal conversion logic.
