HFP: Don't use mSBC for HF devices not supporting Codec Negotiation

* Some misbehaving HF devices (e.g. Sony XAV AX100 carkit, Sony MW600)
  indicate their support on WBS but not support on Codec Negotiation.
  In this condition, if Fluoride chooses mSBC will result in big noise or SCO
  no sound.
* This CL adds a workaround for checking if HF device indicate codec negotiation is
  not supported, Fluoride will assume CVSD codec by default.

Bug: 101592600
Test: make, connect SCO and check voice on carkit and headset.
