Bluetooth: SDP: add one API bt_sdp_get_add_proto_param

Browse source 
The bt_sdp_get_add_proto_param is used to get the protocol
parameter from Additional Protocol Descriptor List.
In order to implement it, one parameter
(proto_profile_index) is added to sdp_get_uuid_data_index
to get the indexed item.
Fix one bug in sdp_get_uuid_data because there may be more
than 2 consequent "seq len item".
