MDEV-16546 System versioning setting to allow history modification

Browse Source 
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.
