MdeModulePkg PlatformVarCleanupLib: Locate VarCheck protocol when using
Do not locate VarCheck protocol in Constructor, then the
gEdkiiVarCheckProtocolGuid could be removed from [Depex].
It will be more flexible for the library Consumer to work without VarCheck
protocol installed, for example at recovery boot mode with EmuRuntimeDxe.
The unused UefiLib is also been removed from [LibraryClasses] in *.inf.
