[fix](Export) fix some issues of Export

[BePPPower]

Proposed changes

Issue Number: close #xxx

1. Forbid rollback to the old optimizer in Export task. Since originStmt is empty, reverting to the old optimizer when the new optimizer is enabled is meaningless.

2. Display parallelism in 'show export'.

3. Create an initial Map for resultAttachedInfo to avoid NullPointerException.

4. Remove the originStmt added in this PR #31020, because the Export statement is underlying the Outfile statement, it cannot be treated as OriginStmt.
