Bluetooth: Add bt_conn_lookup_state function

Browse source 
bt_conn_lookup_state looks up for connection with "peer" in specific
state "state". Returns NULL if there is no connection with peer or
connection state differs from the given one.

Passing BT_ADDR_LE_ANY will return the first connection with the
specific state.
