CMake: Fix Cortex-M33-NS and Cortex-M33 ASM flags

The ASM flags were not supported by armclang, use the armclang alternatives.
Removed armlink --cpu flag as they generate a CMake configuration
time error. Furthermore, it is not necessary to specify the
processor or architecture as the linker auto-detects it from
the input object files.
