Introduce how to name vector function associated to the scalar function decorated with the OpenMP `declare simd` pragma. These vector functions can be used to process multiple instances in a single invocation to improve performance. Both library vendors and compilers must obey this rule to interface with each other.

@kito-cheng Hi, I create a pr and I think we can discuss the name mangling for vector function in here. |

This pr is to introduce how to name the vector function associated to the scalar function decorated with an OpenMP
declare simddirective. It' s important because library vendor and compilers must follow this rule to interface with each other. For example, now risc-v doesn't support libmvec in glibc, if we want to support it, we need to know how to name the vectorized math functions.I have referenced the aarch64 name manling rule
vfabia64in https://github.com/ARM-software/abi-aa/blob/main/vfabia64/vfabia64.rst#vector-function-signature. The main difference is that thelmulin risc-v replace theisain aarch64.
