MDEV-34958: after Trigger doesn't work correctly with bulk insert

Browse Source 
This bug has the same nature as the issues
  MDEV-34718: Trigger doesn't work correctly with bulk update
  MDEV-24411: Trigger doesn't work correctly with bulk insert

To fix the issue covering all use cases, resetting the thd->bulk_param
temporary to the value nullptr before invoking triggers and restoring
its original value on finishing execution of a trigger is moved to the method
  Table_triggers_list::process_triggers
that be invoked ultimately for any kind of triggers.
