codecs: cadence: src: Add support for SRC from Xtensa 

This includes the basic declarations for SRC from Xtensa
support.

It adds the codec id, initializes the API member of
cadence_api with exported library function for SRC and
enables support for linking in the binary codec from Cadence.

All these for the purpose of using Sample Rate Converter
from Xtensa.
