[PATCH V3 0/2] *MdePkg/UefiDevicePathLib: Separate the lib instances

["Gao, Zhichao" <zhichao.gao@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2298

The UefiDevicePathLibOptionalDevicePathProtocolConstructor's implementation
isn't match with its instance name.
Remove the ASSERT and depex of the gEfiDevicePathUtilitiesProtocolGuid
because of "Optional".

Add a mandatory instance to force using the DevicePathUtilities,
DevicePathToText and DevicePathFromText protocol with the ASSERT
and depex.

V2:
The optional lib instance's construction should return success all the
time.
Change the desciption of the optional lib uni file.
Change the copyright date of the mandatory one's uni file.

V3:
Remove the Status variable in UefiDevicePathLibOptionalDevicePathProtocolConstructor.
The Status would cause GCC build fail because the variable is initialized but not used.
Since it is useless for the constructor, directly remove it.
