URL: https://github.com/apache/doris/pull/63379
### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary: PartitionTopN still passed partition key expressions to BE
sort info when the same original slot also appeared in window order keys. These
keys are constant inside each partition, so keeping them causes redundant
comparison work and noisy explain output, especially after slot remapping
changes ExprIds.
### Release note
None
### Check List (For Author)
- Test: Regression test / Unit Test
- Unit Test: env MAVEN_OPTS=-Xmx4g ./run-fe-ut.sh --run
org.apache.doris.nereids.glue.translator.PhysicalPlanTranslatorTest#testPartitionTopNPrunesRemappedPartitionKeyFromSortInfo
- Regression Test: ./run-regression-test.sh --run -d query_p0/explain -s
test_global_partition_topn_plan
- Behavior changed: Yes. PartitionTopN no longer sends redundant partition
key expressions in BE sort info when they refer to the same original slot as a
partition key.
- Does this need documentation: No
