This PR adds SHA-2 assembly implementation for loongarch platforms.
For SHA-256, assembly implementation gets about 20%~ better performance than compiler-generated code.
For SHA-512, assembly implementation also gets a better performance on small-size data, and inot worse on large-size data.
Please see benchmark results below for more details.
Special thanks to @loongson-community/1024 for providing the testing 3A6000 machine.
