Functions make_pathkey_from_sortop() and transformWindowDefinitions(), which receive a SortGroupClause, were determining the sort order (ascending vs. descending) by comparing that structure's operator strategy to BTLessStrategyNumber, but could just as easily have gotten it from the SortGroupClause object, if it had such a field, so add one. This reduces the number of places that hardcode the assumption that the strategy refers specifically to a btree strategy, rather than some other index AM's operators.
