Changed DELETE_WORLD to WORLD_END.

[OzoneH3]

Closes #23688

• Added a simple function to migrate option names from configs.
• Added functionality to migrate string choices.

Please add "reset world" states to the option instead of removing the "delete world" states.
i.e. the option would look something like:

add( "WORLD_END", "world_default", translate_marker( "World end handling" ),
     translate_marker( "Handling of game world when last character dies." ),
     { { "keep", translate_marker( "Keep" ) }, { "reset", translate_marker( "Reset" ) },
       { "delete", translate_marker( "Delete" ) },  { "query", translate_marker( "Query" ) } }, "keep" );

Please don't query maps like that if the key may not be contained in it. This creates a key/value in the map. Use map::find to get an iterator to the existing entry:

const auto iter = mMigrateOption.find( name );
return iter != mMigrateOption.end() ? iter->second : name;

Than you can even make the function const, which it logically should be as it does not change the option_manager object.
