feat: arm64 ASID support

2024-11-24T18:44:34Z

Support for ARM64 ASID to enhance virtual memory management efficiency by reducing the need for TLB flushes during address space switches. These changes improve performance especially for multi-process systems. Changes: - Added `ARCH_USING_ASID` configuration in `libcpu/aarch64/Kconfig`. - Defined ASID-related constants in `mmu.h`. - Updated `TLBI_ARG` macro to include ASID manipulation. - Implemented ASID allocation mechanism with spinlock synchronization. - Enhanced TLB invalidation to support ASID-specific operations. - Modified `rt_hw_aspace_switch` to use ASIDs when switching address spaces. - Adjusted debug logging and function documentation to reflect ASID usage. - Refactored AArch64 MMU and TLB handling for ASID integration.
