selftests/damon: split test cases
Currently, the single test program, debugfs.sh, contains all test cases
for DAMON. When one of the cases fails, finding which case is failed
from the test log is not so easy, and all remaining tests will be
skipped. To improve the situation, this commit splits the single
program into small test programs having their own names.

selftests/damon: test debugfs file reads/writes with huge count
DAMON debugfs interface users were able to trigger warning by writing
some files with arbitrarily large 'count' parameter. The issue is fixed
with commit db7a347b26fe ("mm/damon/dbgfs: use '__GFP_NOWARN' for
user-specified size buffer allocation"). This commit adds a test case
for the issue in DAMON selftests to avoid future regressions.
