    arm/stm32h7: Allow PendSV with high-priority interrupts.
    
    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.
