### What problem does this PR solve?
Related PR: #61092
Problem Summary:
Cherry-pick #61092 to branch-4.0.
In FULL OUTER JOIN queries, MATCH expressions in the SELECT list cannot be
pushed down as filters (this would violate join semantics by incorrectly
filtering rows). This PR enables MATCH expressions used as **projections** to
be pushed down as virtual columns on OlapScan, allowing the BE to evaluate them
via inverted index using the existing `fast_execute()` caching mechanism.
### Release note
Support MATCH expressions as projections pushed down to OlapScan as virtual
columns, enabling inverted index evaluation for MATCH in contexts where it
cannot be pushed as a filter (e.g., FULL OUTER JOIN).
