Issue Number: None

Problem Summary: SHOW CATALOGS passed WHERE expressions to the LIKE pattern
matcher, so valid predicates failed as invalid patterns. Keep LIKE patterns and
WHERE expressions separate, then evaluate WHERE against the privilege-filtered
SHOW rows.
### Release note
Fix SHOW CATALOGS WHERE filtering.
### Check List (For Author)
- Test: Unit Test; regression test added
- Added an FE unit test covering parsing, matching, and non-matching WHERE
predicates.
- Added regression coverage to the existing SHOW CATALOG suite.
- Ran the targeted FE unit test and the full FE build with Checkstyle.
- Behavior changed: Yes. SHOW CATALOGS WHERE now filters the displayed rows.
- Does this need documentation: No
