fix: 修复解析sql条件为global in的问题，补充Clickhouse相关数据库类型的处理

[KANLON]

给SQLParserUtils 工具类，补充Clickhouse相关数据库处理，以免解析 clickhouse 的global in语法的时候报错，
如果不加这个的话，则执行如下代码的时候会报错：

    /**
     * 测试解析sql条件
     */
    @Test
    public void testParseGlobalInSqlCondition() {
        String sql1 = "a global in (select * from t)";
        SQLExpr conditionExpr = SQLUtils.toSQLExpr(sql1, DbType.clickhouse);
        System.out.println(conditionExpr.toString());
    }

报错信息如下：

com.alibaba.druid.sql.parser.ParserException: illegal sql expr : a global in (select * from t), pos 8, line 1, column 3, token IDENTIFIER global
