Bluetooth: host: Add bt_conn_foreach API to iterate all connections

Browse source 
Add iterator function to iterate over all connection objects.
Make type a bitmap so that it can be used as a bitmask to select which
conns to receive foreach callback.
Use foreach function internally where possible.
