Return HAL config in datapath for SwAudioOutputDescriptor

* AudioFlinger needs to return the HAL config opened by Spdif wrappers
  so that AudioPolicyManager can patch with valid port configs.
* AudioPolicyManager openDirectOutput must allow for mismatch of config
  between client request and APM output descriptor config because
  AudioFlinger may format convert using Spdif wrapper.
* When finding or creating a mix port config in Hal2AidlWrapper, we
  need to allow for a client request with DIRECT or IEC958_NONAUDIO
  to match an output without these flags for remote submix, as the
  remote submix HAL may not support those flags and they are not
  necessary for correct remote submix operation.
* Do not use device port config to open stream as fall back for lack
  of profile for opening non-PCM mix port config for remote submix,
  because the remote submix HAL does not support non PCM.

      atest VirtualAudioTest
      (allowing for re-running of flaky tests)
      pass on remote submix AIDL and HIDL HALs.
