selftests/damon: add a test for DAMOS quota
Add a selftest for verifying the DAMOS quota feature. The test is very
similar to sysfs_update_schemes_tried_regions_wss_estimation.py. It
starts an artificial workload of 20 MiB working set, run DAMON to find the
working set size, but with 1 MiB/100 ms size quota. Then, it collect the
DAMON-found working set size every 100 ms and check if the quota was
always applied as expected. For the confirmation, the tests shows the
stat-applied region size and the qt_exceeds stat.
