audio: Add support for QCOM audio devices, formats, and channels

- Add QCOM supported devices, fomats, and input/output
  channels in AudioPolicyManagerBase
- Add QCOM supported devices in AudioSystemLegacy.h

Change-Id: I5e2977a630c2bf9211af62d97ae024c5c57075f9

libhardware_legacy: Add support for DirectTrack

- Add support for DirectOutput in libhardware_legacy
- Add new APIs to AudioStreamOut base class
- Add audio output flags to openOutputStream

audio: add missing QCOM audio devices, formats, and channels

- Add support for FM I/O devices and communication device for VOIP
- Add support for mp2 audio format
- Add support for 6.1 audio channels

Change-Id: I7b3042902c658dc8e5dfa34719fb80d18f3ff4e7

libhardware_legacy: Support LPA Playback

Add support to enable Playback in LPA mode

When Alarm is playing on headset+spkr, if LPA
playback is selected STARTEGY_MEDIA gets selected
and switches device from Combo device to Headset.
- Fix the issue by selecting Combo device only
even incase of LPA when stream ALARM/NOTIFICATION
is active.

Add ifdefs for QCOM enhanced features
