Raghunandan Bhat 2c7cea28da MDEV-31721: Cursor protocol increases the counter of "Empty_queries" for select ...

Problem:
  Empty queries are incremented if no rows are sent to the client in the
  EXECUTE phase of select query. With cursor protocol, rows are not sent
  during EXECUTE phase; they are sent later in FETCH phase. Hence,
  queries executed with cursor protocol are always falsely treated as
  empty in EXECUTE phase.

Fix:
  For cursor protocol, empty queries are now counted during the FETCH
  phase. This ensures counter correctly reflects whether any rows were
  actually sent to the client.

Tests included in `mysql-test/main/show.test`.
