Fix get system setting bug when enabled redis cache (#22295)

Fix #22281

In #21621 , `Get[V]` and `Set[V]` has been introduced, so that cache
value will be `*Setting`. For memory cache it's OK. But for redis cache,
it can only store `string` for the current implementation. This PR
revert some of changes of that and just store or return a `string` for
system setting.
