highgo瀚高数据库不支持Top语法

#### 问题描述及重现代码：
highgo瀚高数据库不支持Top语法，需要使用limit语法替换
```c#
_userRepository.GetAsync(a => a.UserName == req.UserName && a.Password == password && !a.IsDisabled)

最终生成的sql为：
SELECT TOP 1 a.[ID], a.[REVISION], a.[IS_DISABLED], a.[IS_DELETED], a.[GROUP_ID], a.[CREATED_BY], a.[CREATED_BY_NAME], a.[CREATED_TIME], a.[UPDATED_BY], a.[UPDATED_BY_NAME], a.[UPDATED_TIME], a.[USER_TYPE], a.[USER_NAME], a.[DISPLAY_NAME], a.[MOBILE], a.[PASSWORD], a.[MAIL], a.[GROUP_TYPE_ID], a.[PERMISSION_ID], a.[Gender], a.[OPENID], a.[NickName], a.[ERROR_COUNT], a.[LAST_CHANGE_PWD_DATE], a.[IS_LOCK], a.[AVATAR], a.[DESCRIPTION]
FROM [sys_user] a
WHERE (a.[USER_NAME] = N'admin' AND a.[PASSWORD] = N'123456' AND a.[IS_DISABLED] = 0) AND (a.[IS_DELETED] = 0)

需要生成的sql为：
SELECT a.ID, a.REVISION, a.IS_DISABLED, a.IS_DELETED, a.GROUP_ID, a.CREATED_BY, a.CREATED_BY_NAME, a.CREATED_TIME, a.UPDATED_BY, a.UPDATED_BY_NAME, a.UPDATED_TIME, a.USER_TYPE, a.USER_NAME, a.DISPLAY_NAME, a.MOBILE, a.PASSWORD,
a.MAIL, a.GROUP_TYPE_ID, a.PERMISSION_ID, a.Gender, a.OPENID, a.NickName, a.ERROR_COUNT, a.LAST_CHANGE_PWD_DATE, a.IS_LOCK, a.AVATAR, a.DESCRIPTION
FROM sys_user a
WHERE (a.USER_NAME = N'admin' AND a.PASSWORD = N'123456' AND a.IS_DISABLED = 0) AND (a.IS_DELETED = 0)
LIMIT 1
```

#### 数据库版本
瀚高安全版数据库V4.5

#### 安装的Nuget包
FreeSql.All(3.2.808)

#### .net framework/. net core？ 及具体版本
.Net 6

Reproduce the reported GetAsync query against HighGo Security Database V4.5 using FreeSql.All 3.2.808 on .NET 6, then locate the provider's SQL-generation path for this query. The work is done when the HighGo output uses LIMIT 1 instead of SELECT TOP 1 and the query still returns the expected record.
