Add SchemaDumper support table_options for MySQL.

related #12172 

Is often used to specify table_options in MySQL. 

(For example, `"ENGINE=MyISAM"` for full-text search, `"ENGINE=InnoDB ROW_FORMAT=DYNAMIC"` or `"ENGINE=InnoDB ROW_FORMAT=COMPRESSED KEY_BLOCK_SIZE=8"` for use InnoDB of Barracuda File Format.)

SchemaDumper should support a dump of table_options.
This information is based on `information_schema.character_sets`.
