Xin Hao c46b0bb6a7 mm/damon: add 'age' of region tracepoint support
In Damon, we can get age information by analyzing the nr_access change,
But short time sampling is not effective, we have to obtain enough data
for analysis through long time trace, this also means that we need to
consume more cpu resources and storage space.

Now the region add a new 'age' variable, we only need to get the change of
age value through a little time trace, for example, age has been
increasing to 141, but nr_access shows a value of 0 at the same time,
Through this,we can conclude that the region has a very low nr_access
value for a long time.
