Audio: Volume: Add HiFi5 implementation.
Add HiFi5 implementation of volume functions, compared with HiFi3 version, can reduce about 28% cycles.
This is a new merge conflicts fixed version of Andrula's #8900. I've run this successfully in testbench HiFi5 environment with 48 kHz and 44.1 kHz rates with s16 and s32 formats. Though testbench is currently IPC3, so the test didn't exercise IPC4 code parts.
