[DebugInfo] Fix: Variables that have no non-empty values being emitted when they have a DBG_VALUE_LIST

This patch fixes a simple bug where `DbgValueHistoryMap::hasNonEmptyLocation` was incorrectly handling DBG_VALUE_LIST instructions, treating empty values as non-empty, causing empty variables to be emitted into DWARF.
