[PATCH BlueZ] audio/media: Add hfp-hf supported feature flag

["Frédéric Danis" <frederic.danis@collabora.com>]

From: Frédéric Danis <frederic.danis.oss@gmail.com>

This flag is set when HFP HF internal plugin is started.
It allows external applications like PipeWire to know that HFP HF can
be managed by BlueZ and they have to register endpoints for the
supported codecs.
