MDEV-11706 Assertion `is_stat_field || !table || (!table->write_set || bitmap_is_set(table->write_set, field_index) || (table->vcol_set && bitmap_is_set(table->vcol_set, field_index)))' failed in Field_time::store_TIME_with_warning

vcols and triggers. Revert 094f4cf7,
backport the correct fix (Table_triggers_list::mark_fields_used() not
marking vcols) from 10.2.

The function computes the values of the virtual columns of the table and
stores them in the table record buffer.
If vcol_update_mode is set to VCOL_UPDATE_ALL then all virtual column are
computed. Otherwise, only fields from vcol_set are computed: all of them,
if vcol_update_mode is set to VCOL_UPDATE_FOR_WRITE, and, only those with
the stored_in_db flag set to false, if vcol_update_mode is equal to
VCOL_UPDATE_FOR_READ.
