### What problem does this PR solve?

Problem Summary: Implement Iceberg equality delete filtering in the v2
Iceberg reader by materializing equality delete keys as delete predicate
expressions and applying them through the file reader filter path.
### Release note
Support reading Iceberg equality delete files in the BE Iceberg reader.
### Check List (For Author)
- Test: Unit Test / Manual test
- Added EqualityDeletePredicateTest for single-column, multi-column,
null matching, and error handling.
- Manual test: git diff --check.
- Not run: run-be-ut.sh failed because this environment only has JDK 11
and requires JDK 17; clang-format script failed because llvm@16 is not
installed.
- Behavior changed: Yes, Iceberg reader now filters equality-deleted rows.
- Does this need documentation: No
