Support use of DAMOS_FILTER_TYPE_AGE_MS via DAMON sysfs ABI. Add a user keyword "age_ms" for configuring a filter of the type using the existing filter configuration interface. Reuse existing 'min' and 'max' sysfs files in the filter configuration directory for storing the age range in milliseconds.
