### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #63067
Problem Summary:
PR is a Follow-up of #63067 , Extends column-level query/filter hit
recording to cover all major Nereids physical plan constructs beyond the base
PhysicalOlapScan:
- Alias resolution: SELECT k1 AS name records k1.queryHit
- GROUP BY keys: GROUP BY k1 records k1.queryHit
- Aggregate input columns: SUM(k2) records k2.queryHit
- ORDER BY columns: ORDER BY k2 records k2.queryHit
- Window PARTITION BY / ORDER BY keys
- Window value columns: SUM(k2) OVER (...) records k2.queryHit
- JOIN ON conditions (hash + non-equi): records filterHit on both sides
- ROLLUP/CUBE grouping sets via PhysicalRepeat
- PartitionTopN partition and order keys (ROW_NUMBER per-partition)
- Storage-layer aggregate pushdown: COUNT(*)/MIN/MAX queries record stats
- Lazy materialization scan slot remapping via row-id lookup
Out of scope (tracked for Part 3):
The following cases are intentionally deferred and not bugs in this PR:
- UNION / INTERSECT / EXCEPT — set operation output slots are not yet
remapped to child scans
- CTE consumer columns — consumer-side slot IDs differ from producer scan
slots
- LATERAL VIEW / EXPLODE — generator output slots are not yet remapped
- HAVING SUM(k2) > 0 — aggregate output predicates; simple HAVING k1 > 0
already works
- External tables (Hive / Iceberg / JDBC) — deferred, requires separate
design
