### What problem does this PR solve?
Issue Number: close #66273
Related PR: None
Problem Summary: When the optimizer reduces an INSERT INTO SELECT from a
Table Stream to an empty relation, the previous empty-insert shortcut bypasses
the transaction lifecycle. The target receives zero rows, but the stream offset
is not committed, so the same stream state can be read repeatedly. Keep empty
Table Stream reads in the transaction lifecycle, skip coordinator data
execution, and commit the offset atomically. Ordinary empty inserts continue to
use the existing fast-return path.
### Release note
Table Stream offsets now advance when INSERT INTO SELECT succeeds with zero
rows.
### Check List (For Author)
- Test: Unit Test
- InsertIntoTableCommandTableStreamTest and OlapInsertExecutorTest (21
tests)
- ./build.sh --fe -j 192
- Behavior changed: Yes (successful zero-row Table Stream inserts now commit
offsets; ordinary inserts are unchanged)
- Does this need documentation: No
