### What problem does this PR solve?
Related PR: #69419
Problem Summary: Backport #69419 to `branch-4.2`.
Predicate inference copied a predicate on one column to every column that is
equal to it, also when the predicate contained MATCH, multi_match or SEARCH.
Their result depends on the inverted index of the column, not only on its
value: with `c1 = c2` and different parsers on the two columns, the copy
removed matching rows, and with the same index it doubled `score()`, so a
minimum score let low-scored rows through. `InferPredicateByReplace.infer` now
skips every input that contains `Match`, `MultiMatch`, `Search` or
`SearchExpression`.
#### Branch adaptations
The branch does not have the `NoneMovableFunction` check that master has
next to the new check, so only the new check is added. The test imports
`SearchDslParser` from its package on the branch.
### Release note
Fix wrong results and scores when predicate inference copied a MATCH,
multi_match or SEARCH predicate to an equal column.
### Check List (For Author)
- Test
- [x] Regression test
- [x] Unit Test
- [ ] Manual test
- Behavior changed:
- [x] Yes. Predicate inference no longer copies a predicate that
contains MATCH, multi_match or SEARCH to an equal column.
- Does this need documentation?
- [x] No.
### Validation
Validated together with the other two backports (#69399, #69419 and #69292
on `branch-4.2` at ecbc5feab9), in a local ASAN build:
- PASS: FE unit tests `LogicalPlanDeepCopierTest`, `CTEInlineTest`,
`InferPredicateByReplaceTest`, `InferPredicatesTest`,
`UnequalPredicateInferTest`, `BindScoreToOlapScanTest`, `SearchExpressionTest`,
`TopNRuntimeFilterTest`, `PullUpProjectExprUnderTopNTest` and
`MaterializedViewUtilsTest` (280 tests), and FE Checkstyle.
- PASS: `./build.sh --fe --be`.
- PASS: BE unit tests `SegmentIteratorScoreCommonExprTest`,
`SegmentIteratorApplyIndexExprTest` and `VirtualSlotRefTest` (31 tests);
clang-format 16 on the changed BE files.
- PASS: the 23 regression suites of the branch that use `score()`, including
`test_cte_inline_virtual_column`, `infer_match_predicate`,
`test_score_filter_usage` and `test_score_filter_matrix`, with unchanged `.out`
files.
