Subject: [PATCH] [fix](regression) Enable expression pushdown for variant
 norms test

### What problem does this PR solve?

Issue Number: close #68039

Related PR: #68140

Problem Summary: The branch-4.1 regression environment can execute the VARIANT MATCH predicate outside the inverted index when common expression pushdown is not explicitly enabled. MATCH_PHRASE then falls back to execute_match, which is unsupported. Enable common expression pushdown explicitly, matching the existing VARIANT BM25 regression setup.

### Release note

None

### Check List (For Author)

- Test: Regression test configuration fix; TeamCity failure 1051635 reproduces the missing prerequisite
- Behavior changed: No
- Does this need documentation: No
