The irq_offload mechanism was using the same entry of the IDT vector for
all CPUs on SMP systems. This caused race conditions when two CPUs were
doing irq_offload() calls.
This patch addresses that by adding one indirection layer: the
irq_offload() now sets a per CPU entry with the routine and parameter to
be run. Then a software interrupt is generated, and a default handler
will do the appropriate dispatching.
Finally, test "kernel/smp_abort" is enabled for x86 as it should work
now.
Fixes#72172.

Adds a test to verify that a series of k_thread_abort() issued from
ISRs do not cause a deadlock.
Filtered on x86 as the x86_64 irq_offload() implementation isn't
SMP-safe. See #72172
