VELAPLATFO-62486 1. cmake natively supports armclang, and by default it will use the set CMAKE_LINKER link. To adapt to NX's cmake, you need to modify it to use armclang as the linker. 2. Using set(CMAKE_AR armar -rcs) will make cmake recognize the parameter as armar;-rcs, resulting in a compiler error 3. The CPP setting of armclang needs to include --target, otherwise a compilation error will occur and a suitable target cannot be found 4. armclang link cannot use -nostdlib 5. Add --undefined to force linking of the __start symbol, otherwise it will not be referenced and armclang will not be able to find the symbol 6. Fix armclang config 7. armclang cancel the search for libgcc Change-Id: I652f3d1f6ad91e7780729bb255ff649f72d65dd3 Signed-off-by: wangmingrong1 <wangmingrong1@xiaomi.com>

Please update the PR title to the same format as the commit messages.
Also, could please show some logs from a a local build using the new tool chain? I don't think our CI will be able to test that one.

Summary
Impact
1, Enables NuttX/NX to use armclang for CMake/Makefile builds on ARM64, reducing noise warnings from CMake compiler probes.
2, Improves the stability of armclang builds (linker selection, ar parameter parsing, CPP --target, -nostdlib, --undefined __start, libgcc handling, etc.).
3. Expands target coverage for the ARM Cortex-M series (adding cortex-m85), with no expected behavior changes to existing GCC/Clang targets.
