fix(contrib/drivers/mssql): update tables SQL query for better compatibility

[li-zheng-hao]

修复gf gen在sqlserver上的异常问题：

1. gf gen dao 连接sqlserver 生成dao出错 对象名 'SYSOBJECTS' 无效 #1722
2. mssql: 对象名 'SYSOBJECTS' 无效 大小写问题 #1761

> gf gen dao
fetching tables failed: SELECT NAME FROM SYSOBJECTS WHERE XTYPE='U' AND STATUS >= 0 ORDER BY NAME: mssql: 对象名 
'SYSOBJECTS' 无效。
1. SELECT NAME FROM SYSOBJECTS WHERE XTYPE='U' AND STATUS >= 0 ORDER BY NAME
2. mssql: 对象名 'SYSOBJECTS' 无效。

在SqlServer 2022已测试通过：

@li-zheng-hao 你好，我没有在mssql 2022上复现这个问题。如果该问题确实存在，需要提交对应的gf gen dao的单测来覆盖你的修改，保证结果如预期。单测的编写请参考cmd/gf下已有的单测代码：https://github.com/gogf/gf/blob/master/cmd/gf/internal/cmd/cmd_z_unit_gen_dao_test.go

@li-zheng-hao Hello, I did not reproduce this problem on mssql 2022. If this problem does exist, you need to submit a corresponding single test of gf gen dao to cover your modifications and ensure that the results are as expected. For writing single tests, please refer to the existing single test code under cmd/gf: https://github.com/gogf/gf/blob/master/cmd/gf/internal/cmd/cmd_z_unit_gen_dao_test.go
