yinshengkai 54040c6888 libs/libc/machine/arm: add Cortex-M0/M23 support to arch_mcount
Add support for ARMv6-M and ARMv8-M Baseline architectures
(Cortex-M0/M0+/M23) in the mcount profiling function. These cores
only support limited Thumb-1 instruction set and require different
assembly instructions compared to ARMv7-M and higher.

Changes:
- Use MOVS+BICS instead of BIC for bit clearing on M0/M23
- Separate register restore for limited push/pop instructions
- Use BX instead of direct POP to PC on M0/M23
