This commit implements the four essential callbacks of DAMON,
'->init_target_regions', '->update_target_regions',
'->prepare_access_checks', and '->check_accesses' for virtual memory
address spaces.  Those internally use PTE Accessed bit.  Using these
callbacks, users can easily monitor the virtual address space data
accesses of specific processes.  Nonetheless, these are just reference
implementations.  Users can implement and use their own callbacks for
their special use case, if required.
