rtla/osnoise: Leverage IPI event filters when tracing a subset of CPUs
Leverage the kernel event filtering infrastructure to only emit IPI events
if they target CPUs that are being traced, as specified by the -c cmdline
option.
Note that some post-processing is still required for the ipi_send_cpumask
event, as the event being emitted means *some* CPUs targeted by that event
are monitored, but not all of them - userspace has to recompute that
intersection.
