add TiDB parser for parsing DDL

[goccy]

vitess parser has not support fully parsing for DDL.
So use https://github.com/ruiaylin/sqlparser for parsing DDL.
Add directly dependency built package because ruiaylin/sqlparser must compile after downloaded.

support like the following query

CREATE TABLE sample (
  id bigint(20) unsigned NOT NULL,
  other_id bigint(20) unsigned NOT NULL,
  enum_column enum('a','b','c','d') DEFAULT NULL,
  int_column int(10) DEFAULT '0',
  PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

parsing results

&sqlparser.CreateTable{
  DDL: &sqlparser.DDL{
    Action: "create",
    Table:  sqlparser.TableName{
      Name: sqlparser.TableIdent{
        v: "",
      },
      Qualifier: sqlparser.TableIdent{
        v: "",
      },
    },
    NewName: sqlparser.TableName{
      Name: sqlparser.TableIdent{
        v: "sample",
      },
      Qualifier: sqlparser.TableIdent{
        v: "",
      },
    },
    IfExists: false,
  },
  Columns: []*sqlparser.ColumnDef{
    &sqlparser.ColumnDef{
      Name:  "id",
      Type:  "bigint",
      Elems: []string{},
    },
    &sqlparser.ColumnDef{
      Name:  "other_id",
      Type:  "bigint",
      Elems: []string{},
    },
    &sqlparser.ColumnDef{
      Name:  "enum_column",
      Type:  "enum",
      Elems: []string{
        "a",
        "b",
        "c",
        "d",
      },
    },
    &sqlparser.ColumnDef{
      Name:  "int_column",
      Type:  "int",
      Elems: []string{},
    },
  },
}
