[ASTERIXDB-2203][IDX] Eliminate sort operator for secondary primary index
- user model changes: no
- storage format changes: no
- interface changes: no
details:
This change is intended to remove the sort operator when creating
a secondary primary index. The secondary primary index DDL statement uses
the same code as the one for creating general secondary BTree indexes which
has the sort operator since it needs to sort by SK. The sort operator is
not needed for secondary primary index since there is no SK and PK is already
sorted.
