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.

�，修复rtc编译报错 (#9583)

When RT_USING_DEBUG is disabled, variables used only in RT_ASSERT
statements become unused, triggering -Wunused-but-set-variable compiler
warnings. These variables are essential for runtime assertions in debug
builds but appear unused in release builds.
Example:
- Variables used in RT_ASSERT(var != RT_NULL) checks
- Affects multiple drivers and components using RT_ASSERT
This is a general cleanup to improve code compilation without affecting
functionality.

This patch addresses a use-after-free (UAF) vulnerability in the
sys_mount. The issue occurred due to improper handling of memory
deallocation, which could lead to crashes or undefined behavior on user
request of mounting.
Changes made:
- Moved the `rt_free(copy_source)` function call to occur after the necessary
operations are completed, preventing premature deallocation of memory.

* (fix) mmu: satp value should be 64-bit
Corrected the SATP register to ensure it uses the correct 64-bit format as required by the system architecture.
* use __asm__ instead of asm for the GNU C compiler

This patch improves the atomicity of context switching by ensuring that
the stack pointer (sp) and thread self updates occur simultaneously.
This enhancement is crucial for maintaining thread safety and
preventing potential inconsistencies during context switches.
Changes:
- Modified `cpuport.h` to use `ARM64_THREAD_REG` for thread self access.
- Added an `update_tidr` macro in `context_gcc.S` to streamline thread ID
updates.
- Adjusted `rt_hw_context_switch_to` and `rt_hw_context_switch` to call
`update_tidr`, ensuring atomic updates during context switches.
- Cleaned up `scheduler_mp.c` by removing redundant thread self
assignments.
