Performance Optimization of SM4-CBC Encryption and Decryption with Assembly on RISC-V Architecture

(Merged from #29137)

Added assembly implementation for SM4-CBC encryption and decryption. The code adopts a block processing approach, dynamically selecting different blocks for batch processing based on data length. The encryption function supports 4-block and single-block modes, while the decryption function supports 8-block, 4-block, and single-block modes. After optimization, the performance of both encryption and decryption has been enhanced.

Test Verification
```
make test

All tests successful.
Files=343, Tests=3669, 2003 wallclock secs (321.33 usr 246.33 sys + 9286.09 cusr 4460.92 csys = 14314.67 CPU)
Result: PASS
```

The average result was taken from three test runs performed on a RISC-V virtual machine featuring the Zvksed extensions.

Performance Improvement
```

openssl speed -elapsed -seconds 3 -evp sm4-cbc
openssl speed -decrypt -elapsed -seconds 3 -evp sm4-cbc
