Add API to retrieve Audio Product Strategy from a given Audio Attributes

In order to ensure only one matching algorithm is implemented in the
audio policy engine, we cannot use the list of audio product strategy
to let the client of this API inferring the product strategy to use.
It shall request the audio policy manager which product strategy shall be
followed by a given Audio Attributes.
