When outputting json:
* Don't truncate numbers.
* Report address of iocg to ease drilling down further.
When outputting table:
* Use math.ceil() for delay_ms so that small delays don't read as 0.

Json has limited accuracy for numbers and can silently truncate 64bit
values, which can be extremely confusing. Let's consistently use
string encapsulated values for json output.
While at it, convert an unnecesary f-string to str().

Instead of mucking with debugfs and ->pd_stat(), add drgn based
