MDEV-35237 Bulk insert fails to apply buffered operation during CREATE..SELECT statement

Browse Source 
Problem:
=======
- InnoDB fails to write the buffered insert operation during
create..select operation. This happens when bulk_insert
in transaction is reset to false while unlocking a source table.

Fix:
===
- InnoDB should apply the previous buffered changes to
all tables if we encounter any statement other than
pure INSERT or INSERT..SELECT statement in
ha_innobase::external_lock() and start_stmt().

- Remove the function bulk_insert_apply_for_table()

start_stmt(), external_lock(): Assert that trx->duplicates
should be enabled during bulk insert operation
