[PATCH V2 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.
