mm/damon/core: implement PSI metric DAMOS quota goal
Extend DAMOS quota goal metric with system wide memory pressure stall
time. Specifically, the system level 'some' PSI for memory is used. The
target value can be set in microseconds. DAMOS measures the increased
amount of the PSI metric in last quota_reset_interval and use the ratio of
it versus the user-specified target PSI value as the score for the
auto-tuning feedback loop.
