### What problem does this PR solve?
Issue Number: None
Related PR: #66345
Problem Summary:
`rewrite_data_files` fails with `Iceberg table schema changed after the
write was bound` on any table whose column has a write default. The rewrite
binds the cached read schema, which carries no write default, so the default
comparison always mismatches.
A default materialized at bind is an ordinary written value, so a later
default change cannot corrupt the write. This PR stops comparing write
defaults, matching Spark. Name, type, field-id and column-order checks are kept.
### Release note
Fix `rewrite_data_files` failing on Iceberg tables with column write
defaults.
### Check List (For Author)
- Test
- [x] Regression test
- [x] Unit Test
- [ ] Manual test (add detailed scripts or steps below)
- [ ] No need to test or manual test. Explain why:
- [ ] This is a refactor/code format and no logic has been changed.
- [ ] Previous test can cover this change.
- [ ] No code files have been changed.
- [ ] Other reason
- Behavior changed:
- [ ] No.
- [x] Yes. A concurrent write-default change no longer makes
INSERT/UPDATE/MERGE retry; they write the default seen at analysis, as Spark
does.
- Does this need documentation?
- [x] No.
- [ ] Yes.
