mm/damon/core: introduce DAMOS_QUOTA_GOAL_TUNER_TEMPORAL
Introduce a new goal-based DAMOS quota auto-tuning algorithm, namely
DAMOS_QUOTA_GOAL_TUNER_TEMPORAL (temporal in short). The algorithm aims
to trigger the DAMOS action only for a temporal time, to achieve the goal
as soon as possible. For the temporal period, it uses as much quota as
allowed. Once the goal is achieved, it sets the quota zero, so
effectively makes the scheme be deactivated.
