Eight-core boot on SpacemiT K1 could stall with one CPU in the
unlock LR/SC loop, two CPUs allocating tickets, and the remaining
CPUs waiting for the scheduler lock.
Replace LR/SC ticket allocation with amoadd.w.aqrl and release the
lock with a halfword owner update. Order critical-section accesses
after acquiring ownership and before releasing it.
Verified eight-core boot on K1 with temporary diagnostics and
reservation-clearing changes removed.

* [libcpu][risc-v] Refactor the RISC-V architecture port
Introduce an opt-in unified RISC-V common layer for RV32 and RV64 while keeping existing BSPs on the legacy implementation during migration.
- use ARCH_RISCV and ARCH_CPU_64BIT for architecture and XLEN selection
- unify context, trap, MMU, cache, timer, SBI, SMP and ISA handling
- add PLIC, CLIC, ACLINT, APLIC and IMSIC support
- map physical hart IDs to contiguous logical CPU IDs
- add T-Head vendor overrides while preserving legacy ports
- migrate qemu-virt64-riscv with RV32 and RV64 support
- update clock_time, MM, LWP, OFW, PCI and Rust integration
Existing BSPs continue using legacy_common or common64 unless they select RT_USING_RISCV_NEW_COMMON.

* [libcpu][risc-v] skip disabled CPU nodes in early FDT walk
Rbb666 noted that rt_hw_fdt_install_early() walked every /cpus child
without checking status, so disabled cores still joined hart registration
and MMU capability probing. Skip nodes that are not okay/ok via
rt_fdt_device_is_available() before reading reg or mmu-type.

* [libcpu][risc-v] Fix per-CPU page table mapping
- reuse existing non-leaf page table entries when mapping per-CPU areas
- reject leaf entry conflicts instead of overwriting mappings

提供一份公共代码于common (#6941)
整合libcpu/riscv中的移植文件 提供一份公共代码于common
在提交本pr时，除hpmicro的内核，rv32内核bsp已完成去除大部分的冗余，大部分代码采用common中的实现。本pr的作用是进一步统一common中的文件，从而提供一份公用代码，新移植的RV32内核的BSP可以全部使用common代码。
- 在common中提供一份公用文件：interrupt_gcc.S
- 修改原有的文件，将原有的中断中上下文切换代码替换为interrupt_gcc.S
- 基于上述修改，修改仓库中risc-v内核的BSP与移植相关的部分 (主要包含中断入口函数 中断栈等)
- 在common中提供一份公用文件：trap_common.c；提供统一中断入口函数，中断入口函数初始化，中断入口注册等函数，并完善异常时的信息输出
- 在common中提供一份公用文件：rt_hw_stack_frame.h；将栈帧结构体剥离，供用户使用
- 在上述工作完成后，在上述工作的基础上测试仓库中risc-v内核的BSP
- 完善函数中的命名，完善中断栈的获取
- 提供一份详细的基于现有common文件的移植指南
#### 在什么测试环境下测试通过
- 1.CH32V307V-R1-R0
- 2.CH32V208W-R0-1V4
- 3.HPM6750EVKMINI
- 4.GD32VF103V-EVAL
- 5.qemu(CORE-V-MCU )
> 与上述开发板使用同样芯片的BSP均测试通过
在CH32V307V-R1-R0与HPM6750EVKMINI上基于现有移植文件进行多线程复杂场景下的长时间测试，测试过程系统运行正常。
