[RISCV] Implement multi-lib reuse rule for RISC-V bare-metal toolchain (#73765)
Extend the multi-lib re-use selection mechanism for RISC-V.
This funciton will try to re-use multi-lib if they are compatible.
Definition of compatible:
- ABI must be the same.
- multi-lib is a subset of current arch, e.g. multi-lib=march=rv32im
is a subset of march=rv32imc.
- march that contains atomic extension can't reuse multi-lib that
doesn't has atomic, vice versa. e.g. multi-lib=march=rv32im and
march=rv32ima are not compatible, because software and hardware
atomic operation can't work together correctly.
