SecurityPkg/TcgMor: move TPer Reset operation to this module

The TPer Reset operation is a common logic. So it's added into
SecurityPkg/Tcg/MemoryOverwriteControl/TcgMor.inf module and
would be triggered at EndOfDxe.

By this way, all encrypted drives which produce EFI_STORAGE_SECURITY_
RPOTOCOL interface would be force reset when MOR is set.
