As shown in (DEFALUT | GENERIC_ARGUMENT)_UAST, UAST's PsiType mapping needs an automatic expansion of type alias. This commit makes utils that generate optimal type mapping modes for return / parameter to consider if this is used for UAST. In that case, utils will set `mapTypeAliases` true so that typealias (even inside type arguments) can be expanded properly.
