kernel/sched: Don't make an IPI if we don't need it

Browse source 
If an architecture declares support for IPI, we still want to use it
only when running in SMP mode.

(This also fixes a build failure on ARC, which declares
CONFIG_SCHED_IPI_SUPPORTED but doesn't actually implement
z_arch_sched_ipi() yet).
