Parser: support storage engine and VALUE IN MAXVALUE

[yangwenmai]

What problem does this PR solve?

fix issues: #500

MySQL Syntax:
ALTER TABLE ..., ADD PARTITION ( PARTITION ... STORAGE ENGINE text_string ...)

Bad Case

ALTER TABLE d_n.t_n WITHOUT VALIDATION , ADD PARTITION ( PARTITION ident VALUES LESS THAN ( MAXVALUE ) STORAGE ENGINE text_string MAX_ROWS 12 );
ALTER TABLE d_n.t_n WITH VALIDATION , ADD PARTITION NO_WRITE_TO_BINLOG (PARTITION ident VALUES LESS THAN MAXVALUE STORAGE ENGINE = text_string, PARTITION ident VALUES LESS THAN ( MAXVALUE ) (SUBPARTITION text_string MIN_ROWS 11));
ALTER TABLE d_n.t_n WITHOUT VALIDATION , ADD PARTITION ( PARTITION ident VALUES IN ( MAXVALUE ) STORAGE ENGINE text_string MAX_ROWS 12 );
ALTER TABLE d_n.t_n WITH VALIDATION , ADD PARTITION NO_WRITE_TO_BINLOG ( PARTITION ident VALUES IN ( MAXVALUE ) STORAGE ENGINE text_string MAX_ROWS 12 );
ALTER TABLE d_n.t_n WITH VALIDATION , ADD PARTITION NO_WRITE_TO_BINLOG (PARTITION ident VALUES LESS THAN MAXVALUE STORAGE ENGINE = text_string, PARTITION ident VALUES IN ( MAXVALUE ) (SUBPARTITION text_string MIN_ROWS 11));
