What problem does this PR solve?

Issue Number: close #44477

Problem Summary:
Close record set for select stmt and insert/update stmt is in different code path.
Miss calling resetCTEStorage for insert/update stmt, whose recordSet is nil.

What is changed and how it works?

  1. call resetCTEStorage() in handleNoDelay(), this will cover insert/update.. DML stmt.
  2. call resetCTEStorage() in (a *ExecStmt) CloseRecordSet`, this will cover select stmt. Also for prepare/execute/plan cache/select for update.
