Lance Add 1682cc98bb feat(gdb): Allow to set table field metadata and allow to generate table fields registration code when generating dao (#4460) ...

`gdb`在第一次查询时会拉取一次`table`的`fields meta`信息，为后续orm的字段过滤和时间特性服务，`gen
dao`时已经获得了`table`的所有`fields
meta`，提供一个生成`table`的功能，允许客户自行决定是否生成，是否注入已知表结构缓存到指定`db`实例。
1. 能解决部分兼容`mysql`的二开数据库在获取`fields meta`时无法和`mysql`保持一致的问题。
2.
可以模拟表字段信息而不需要真实的数据库连接，对于已知的表结构，可以直接设置缓存，在无法连接数据库的情况下，仍然可以使用表字段信息，使用gdb构建sql时不需要受限于实际数据库即可使用`gdb.ToSQL()`方法。
4. 提升访问速度
