Fix syntax error position indicators in parameters queries

To fix #2193 prefix_length member variable has been added to ParsedURL
that is set to the length of "/service/version/profile/" prefix
when the prefix is accepted by the parser.
Also BOOST_FUSION_ADAPT_STRUCT for osrm::server::api::ParsedURL
has been moved from header to url_parser.cpp to speed up compilation
of CUs that do not use the fusion adaption.
