MDEV-12930 Testing SEQUENCE object

Browse Source 
Fixed the following things from the above MDEV:
- Ensure the user has INSERT privilege when generating new sequence values
  with NEXT VALUE FOR or SETVAL()
- Fixed bug in InnoDB when generating several sequence values in one statement
- Ensure that read_set is up to date before calling ha_sequence::ha_write_row()
  - This is only a potential bug with storage engines that trusts the column maps completely
