mm/damon/core: introduce nr_accesses_bp
Add yet another representation of the access rate of each region, namely nr_accesses_bp. It is just same to the nr_accesses but represents the value in basis point (1 in 10,000), and updated at once in every aggregation interval. That is, moving_accesses_bp is just nr_accesses * 10000. This may seems useless at the moment. However, it will be useful for representing less than one nr_accesses value that will be needed to make moving sum-based nr_accesses.
