Leave AudioProfileVector only in libaudiofoundation.

Make AudioProfileVector only in libaudiofoundation. In policy part,
instead of having policy specific AudioProfileVector deriving from
AudioProfileVector in libaudiofoundation, make all the functions as
global functions. In that case, AudioPortBase does not need to be a
template class. That helps make the structure clearer.

Test: audio smoke test
Test: CTS for AudioTrack, AudioRecord, AudioManager
