mm/damon/lru_sort: support young page filters

DAMON monitors access patterns at the region level, and hence there could
be some page level mismatches.  A few hot pages could be located in cold
regions, and vice versa.  Young page filters can be useful for doing
additional page level access checks before applying some DAMOS action.

DAMON_LRU_SORT is not using young page filters, though.  Add a parameter
for using it.
