arch/common: Provide a weak, generic z_arch_irq_connect_dynamic()

Browse source 
It was discovered that the xtensa version of
z_arch_irq_connect_dynamic() was being removed along with the old
xtensa architecture support, because it was never included in the asm2
builds.

But there's no xtensa-specific code in it at all.  Architectures that
use the existing sw_isr_table mechanism and don't (or can't, in the
case of xtensa which has fixed interrupt priority) interpret the other
parameters might as well have access to a working generic
implementation.

Fixes #18272
