[mlir] Fix CallOpInterface extraClassDeclaration

[RIscRIpt]

extraClassDeclaration of CallOpInterface can be inherited by other OpInterfaces into foreign namespaces, thus types must be fully qualified to prevent compiler errors, for example:

def MyCaller : OpInterface<"MyCaller", [CallOpInterface]> {
    let cppNamespace = "::MyNamespace";
}

Thanks! I don't have write access, but I believe it is ready to be merged.
