Get the GsymCreator string table offset for the qualified name for the DIE passed in.

This function will avoid making copies of any strings in the GsymCreator when possible. We don't need to copy a string when the string comes from our .debug_str section or is an inlined string in the .debug_info. If we create a qualified name string in this function by combining multiple strings in the DWARF string table or info, we will make a copy of the string when we add it to the string table.
