arch: arm64: initialize IRQ stack for CONFIG_INIT_STACKS
When CONFIG_INIT_STACKS is enabled all stacks should be filled with 0xaa
so that the thread analyzer can measure stack utilization, but the IRQ
stack was not filled and so `kernel stacks` on the shell would show that
the stack had been fully used and inferring an IRQ stack overflow
regardless of the IRQ stack size.
Fill the IRQ stack before it gets used so that we can have precise usage
reports.
