These changes introduce the rt_interrupt_context family, providing a mechanism for managing nested interrupts. The context management ensures proper storage and retrieval of interrupt states, improving reliability in nested interrupt scenarios by enabling context tracking across different interrupt levels. This enhancement is essential for platforms where nested interrupt handling is crucial, such as in real- time or multi-threaded applications. Changes: - Defined rt_interrupt_context structure with context and node fields in `rtdef.h` to support nested interrupts. - Added rt_slist_pop function in `rtservice.h` for simplified node removal in singly linked lists. - Declared rt_interrupt_context_push, rt_interrupt_context_pop, and rt_interrupt_context_get functions in `rtthread.h` to manage the interrupt/exception stack. - Modified AArch64 CPU support in `cpuport.h` to include rt_hw_show_register for debugging registers. - Refactored `_rt_hw_trap_irq` in `trap.c` for context-aware IRQ handling, with stack push/pop logic to handle nested contexts. - Implemented interrupt context push, pop, and retrieval logic in `irq.c` to manage context at the CPU level.
