fa9d4f1 
…oin pushdown (#61635)

Push PreferPushDownProject expressions to the matching join child as
aliases and replace them with slots in filter predicates. This keeps OR
predicates above join while exposing nested-field access below join for
storage-level pruning acceleration.

Plan tree demo:

Before:
```
  LogicalFilter((match_any(info['context'], 'abc') OR r.k2 > 60))
    LogicalJoin(INNER)
      left:  LogicalOlapScan(student)
      right: LogicalOlapScan(score)
```

After:
```

  LogicalFilter((slot#x OR r.k2 > 60))
    LogicalJoin(INNER)
      left:  LogicalProject(student.*, match_any(info['context'], 'abc') AS slot#x)
                  LogicalOlapScan(student)
      right: LogicalOlapScan(score)
```
