MdePkg: Fix SafeString performing assertions on runtime checks
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2054
Runtime checks returned via status return code should not work as
assertions to permit parsing not trusted data with SafeString
interfaces. Replace ASSERT() with a DEBUG_VERBOSE message.
