leaudio: Speed up reconfiguration between Conversational and Media 

To avoid sending Media on the CISes for CONVERSATIONAL, and also
Ringtone on the CISEs for Media, BT stack will reconfigure stream
whenever TBS calls SetInCall().

Flag: com.android.bluetooth.flags.leaudio_speed_up_reconfiguration_between_call
