Convert IRQ-related macros to static inline functions and introduce
wrappers for arch-specific implementations. This follows the style we
defined for multi-arch development.
This is a follow-up update for commit
a7239d126 ("[FIXME] hv: risc-v add denpended implementation in cpu.h").
CPU_IRQ_ENABLE_ON_CONFIG -> local_irq_enable
CPU_IRQ_DISABLE_ON_CONFIG -> local_irq_disable
CPU_INT_ALL_DISABLE -> local_irq_save
CPU_INT_ALL_RESTORE -> local_irq_restore
