CAudioInput/Output: Apply VoIP latency in case of VoIP audio type

There was no implementation of setting specific latency value except default case.
An audio type can be set by audio_in[out]_set_sound_stream_info() and therefore
we can utilize the audio type to determine which latency type should be set.
If it is set, the audio core recoginizes it and set this stream with a specific
latency value.

VoIP type is one of the most common usecases for audio-io API. This case is
now added.
