* [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
