schemeshard: reject operations with too big local tx commit (#6760)

Add commit redo size check for successfully ignited operations as a precaution measure to avoid infinite loop of schemeshard hitting local tx commit redo size limit, restarting, attempting to propose persisted operation again, hitting commit redo size limit again, restarting and so on.

This could happen with inherently massive operations such as copy-tables used as a starting step of database export/backup.

Coping large number of tables with huge number of partitions can result in so large TTxOperationPropose local transaction that its size would hit the limit imposed by the tablet executor. Tablet violating that limit is considered broken and will be immediately stopped.
See ydb/core/tablet_flat/flat_executor.cpp, NTabletFlatExecutor::TExecutor::ExecuteTransaction().
