libcpu: riscv: fixed ARCH_RISCV_VECTOR issue
description: Using the vector instruction set to trigger
an illegal instruction exception when ARCH_SISCV_VECTOR=y.
analysis: When initializing the thread stack,
the rt_cw_stack_init function did not enable VS for SSTATUS.
Solution: When ARCH_SISCV_VECTOR=y,
increment the initial value of sstatus by 0x600(SSTATUS_VS).
