FM: Add backward compatiblity support for oreo FM configs

* Due to 43bf623710ab5376d98a143ad64f35c9f12d8d95 and some others CAF is
  completely using audioManager get/setParameters to set DEVICE_OUT_FM for FM
  audio path, but on older devices with oreo mixer paths and kernel drivers
  this doesn’t work and breaks audio output although FM recording works.
* “ro.vendor.fm.use_audio_session” prop is for using AudioTrack session to set
  audio path.

Patch was ported to Q due to these commits
