MDEV-16546 System versioning setting to allow history modification
1. system_versioning_insert_history session variable allows pseudocolumns ROW_START and ROW_END be specified in INSERT, INSERT..SELECT and LOAD DATA. 2. Cleaned up select_insert::send_data() from setting vers_write as this parameter is now set on TABLE initialization. 4. Replication of system_versioning_insert_history via option_bits in OPTIONS_WRITTEN_TO_BIN_LOG.
