kernel/debug: Report team/thread exit status

Browse Source 
Add a field to `debug_[team/thread]_deleted` to report the exit status
on the corresponding events.

This is useful for debuggers like GDB expecting a return value when one
of their inferiors quit.

Also add a `usage` field to `debug_team_deleted` since this is another
potentially useful piece of information exposed by the `waitpid` family
of syscalls.
