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.
I'm not sure about this method. It's doing a lot of work to parse and detect missing collation and to compare with default table options, but it seems it could safely return the verbatim table options that MySQL tells us.
