With CONFIG_ARCH_HIPRI_INTERRUPT enabled, arm_doirq() dispatches PendSV
for deferred processing. The STM32H7 debug handler unconditionally panics
on that valid interrupt, preventing normal operation with debug enabled.

Guard the panic with CONFIG_ARCH_HIPRI_INTERRUPT, allowing the common
interrupt path to finish signal delivery and context switching. Preserve
the diagnostic when high-priority interrupts are disabled.
