### What problem does this PR solve?
Issue Number: None
Related PR: #69679
Problem Summary:
Backport #69679 to branch-4.2. Constant expressions such as COALESCE can
return ordinary single-row columns, while scan predicate processing assumes
ColumnConst and fails a checked cast. Normalize cached results with
ConstantExprResult and migrate scan, scalar-function and ANN consumers,
preserving NULL handling and constant broadcasting.
Adapt regexp consumers and scan tests to the 4.2 interfaces without
importing unrelated master features.
### Release note
Fix query errors when scan predicates use constant expressions that return
ordinary single-row columns.
### Check List (For Author)
- Test
- [x] Unit Test: ASAN BE build passed; 197 targeted tests across 13
suites ran, 196 passed and the existing MathFunctionTest.random_test was
skipped. Coverage includes constant ownership/broadcasting, NULL scan
predicates, LIKE, scalar constant arguments and ANN.
- clang-format 16 and whitespace checks passed.
- clang-tidy scanned 28 changed translation units; the existing
unmatched NOLINTEND in core/types.h prevents a clean pass. No additional
diagnostics on changed lines.
- Validation used the automation prebuilt third-party package with
verified SHA256 and checked Paimon C API compatibility;
Paimon/snappy/librdkafka versions differ from the branch defaults. Connector
runtime and SQL regression tests were not run.
- Behavior changed:
- [x] Yes. Scan consumers accept ordinary single-row constant results.
- Does this need documentation?
- [x] No.
