…te fail because of invalid slot (apache#58643)
Related PR: apache#57558apache#58413
Problem Summary:
This fix addresses the following three issues:
1. When invoking the method
org.apache.doris.nereids.trees.plans.logical.LogicalHudiScan#withRelationId,
the output needs to be recalculated to meet expectations.
2. After compensating with a union all due to partial partition
invalidation of a materialized view, during the next round of
transparent rewriting, the rewriting for the child of the union
allshould use the query partitioncorresponding to the specific relation
id to prevent infinite loops.
3. Currently, in the `test_hudi_rewrite_mtmv` test, if the plan
rewritten by the materialized view transparent rewriting is not selected
by the CBO, it is difficult to troubleshoot because explain memo planis
not used. Therefore, the corresponding test method is modified.

Please clearly describe your PR:

  1. What problem was fixed (it's best to include specific error reporting information). How it was fixed.
  2. Which behaviors were modified. What was the previous behavior, what is it now, why was it modified, and what possible impacts might there be.
  3. What features were added. Why was this function added?
  4. Which code was refactored and why was this part of the code refactored?
  5. Which functions were optimized and what is the difference before and after the optimization?
