Bluetooth: Audio: Remove bidirectional audio streams

Browse source 
Audio streams as defined by the BAP spec does not
support bidirectional audio streams. This commit
updates the API and implementation to match that.

The use a bidirectional CIS with 2 audio stream will
be added in a future commit.

This removes the _IN_ and _OUT_ and _INOUT_ QOS
values, as well as the direction of the codec QOS
struct.

To keep direction for internal use, the direction
has been added to the endpoint struct.
