mm/damon/core: implement intervals auto-tuning
Implement the DAMON sampling and aggregation intervals auto-tuning
mechanism as briefly described on 'struct damon_intervals_goal'. The core
part for deciding the direction and amount of the changes is implemented
reusing the feedback loop function which is being used for DAMOS quotas
auto-tuning. Unlike the DAMOS quotas auto-tuning use case, limit the
maximum decreasing amount after the adjustment to 50% of the current
value, though. This is because the intervals have no good merits at rapid
reductions since it could unnecessarily increase the monitoring overhead.
