trace: Add trace_ipi_send_cpumask()
trace_ipi_raise() is unsuitable for generically tracing IPI sources due to
its "reason" argument being an uninformative string (on arm64 all you get
is "Function call interrupts" for SMP calls).
Add a variant of it that exports a target cpumask, a callsite and a callback.
