Refactor system setting (#27000) (#27452)
Backport #27000 by @wxiaoguang

This PR reduces the complexity of the system setting system.

It only needs one line to introduce a new option, and the option can be
used anywhere out-of-box.

It is still high-performant (and more performant) because the config
values are cached in the config system.
