feat(meta-edit): support composite types via + separator

Build-TypeContentXml / build_type_content_xml now detect " + " in type
string, split into parts and recursively generate separate <v8:Type>
entries with qualifiers for each type. JSON DSL supports type as array.

Also fix reference types to use local xmlns:d5p1 declaration instead of
root-level cfg: prefix — prevents "Неизвестное имя типа" build errors.
