MDEV-11092 Assertion `!writer.checksum_len || writer.remains == 0' failedbb-mdev-11092

Problem:-
This crash happens because logged stmt is quite big and while writing
Annotate_rows_log_event it throws EFBIG error  but we ignore this error
and do not call cache_data->set_incident().

Solution:-
When we normally write Binlog_log_event we check for error EFBIG, but we did
do this for Annotate_rows_log_event. We check for this error and call
cache_data->set_incident() accordingly.
