selftests/damon/drgn_dump_damon_status: dump ctx->ops.id

Browse source 
drgn_dump_damon_status.py is a script for dumping DAMON internal status in
json format.  It is being used for seeing if DAMON parameters that are set
using _damon_sysfs.py are actually passed to DAMON in the kernel space. 
It is, however, not dumping full DAMON internal status, and it makes
increasing test coverage difficult.  Add ctx->ops.id dumping for more
tests.
