Introduce target dirty segment ratio tunable parameter

We introduce a new parameter of target dirty segment ratio,
which can be used to set a target dirty / (dirty + free) segments
ratio. For example, if we set this as 80%, GC sleep time will be
calculated to achieve this ratio in a GC period.

Bug: 241601436
Test: check smart idle maint log of StorageManagerService
