SecurityPkg/PlatformSecureLibNull: permit use by MM_STANDALONE modules

Add MM_STANDALONE to the list of module types that are permitted to
link to this library. Also, since the constructor prototype is
different between MM_STANDALONE and DXE_DRIVER type libraries,
convert the library into BASE type.
