Add different logger support for cup.log.xxx

**Describe the bug** 清晰简洁的BUG描述

Only 1 default logger is supported in cup.log.xxxx, need to set up different loggers especially for ad-hot debugging.

Start by reading the cup.log.xxxx implementation and determine how its single default logger is configured. Clarify the required interface and behavior for multiple loggers, especially for ad-hot debugging, then verify that separate logger setup works without breaking the existing default behavior.
