hfpmodem: Add support for sending the supported codecs 

Right now, only the mandatory CVSD codec is supported. The mSBC
mandatory codec is "temporarily" not supported.

The spec alows this, HFP 1.6 Spec Section 4.34.1 page 92: "If wide band
speech is supported then the mandatory codec (mSBC) shall be included
unless it is temporarily unavailable."
