* feat: logx support logs rotation based on size limitation. (#1652)

Totally compatible with the old logx.LogConf. No effect if users do not change their options.

- `Compress`: 是否压缩日志文件，只在 `file` 模式下工作
- `KeepDays`：日志文件被保留多少天，在给定的天数之后，过期的文件将被自动删除。对 `console` 模式没有影响
- `StackCooldownMillis`：多少毫秒后再次写入堆栈跟踪。用来避免堆栈跟踪日志过多
- `MaxBackups`: 多少个日志文件备份将被保存。0代表所有备份都被保存。当`RotationRuleType`被设置为`LogRotationRuleTypeSizeLimit`时才会起作用。注意：`KeepDays`选项的优先级会比`MaxBackups`高，即使`MaxBackups`被设置为0，当达到`KeepDays`上限时备份文件同样会被删除。
- `MaxSize`: 当前被写入的日志文件最大可占用多少空间。0代表没有上限。单位为`MB`。当`RotationRuleType`被设置为`LogRotationRuleTypeSizeLimit`时才会起作用。
- `RotationRuleType`: 日志轮转策略类型。默认为`LogRotationRuleTypeDaily`（按天轮转）（整形数值0）。
- `LogRotationRuleTypeDaily`（整形数值0）: 按天轮转。
- `LogRotationRuleTypeSizeLimit`（整形数值1）: 按日志大小轮转。
