profiler doesn't take interrupt time into account

Description
Even after recent fixes, the profiler still seems to miss a lot of ticks. One potential source of these missed ticks may be time spent in interrupt handlers. At present, the scheduler does track this time, but it's stored in an internal field and not exported into the thread data like kernel_time and user_time.
Note:
See TracTickets
for help on using tickets.
Windows task manager have separate interrupt time statistic. It would be nice to have something similar in Haiku too (show it in ProcessController).
