[fix](iceberg) Execute empty static overwrite and stabilize info_schema timezone test

[suxiaogang223]

What problem does this PR solve?

Issue Number: None

Related PR: #62344

Problem Summary: Pick #62344 from branch-4.1 to master. The source PR fixes Iceberg static partition overwrite when the source query is optimized to an empty relation, and stabilizes the information_schema.rowsets timezone regression case. git cherry showed the three source commits were not present on origin/master, so this PR applies them to master. The only pick conflict was in test_information_schema_timezone.groovy; the resolution keeps the current master offset timezone coverage and applies the stable rowsets query helper from the source PR.

Release note

Fix Iceberg static partition overwrite when the source query is empty.

Check List (For Author)

• Test: Manual test
  • git diff --check origin/master..HEAD
• Behavior changed: Yes. Empty-source Iceberg static partition overwrite can execute the overwrite path instead of being skipped as empty.
• Does this need documentation: No
