MLK-24255-2 ASoC: SOF: Introduce POST_PROCESS component type

POST_PROCESS component takes care of processing algorithms. For now,
we intend to use this component for decoding/encoding library algorithms
from Cadence.

Current implementation assumes that we will still use ALSA PCM
interface. The heavy part is done on firmware side with the help
of topology files.
