FatPkg/EnhanceFatDxe:Deprecate EFI_UNICODE_COLLATION_PROTOCOL_GUID

Browse source 
EFI_UNICODE_COLLATION_PROTOCOL_GUID was deprecated in favor of
a newer version EFI_UNICODE_COLLATION_PROTOCOL2_GUID which
provides improved language support and better extensibility.

It was officially removed from UEFI specifications
2.10A and 2.11 and should no longer be used in
current implementations.
