[ffigen] Support passing C++ classes by value #3603
Description
We could support passing C++ classes by value by converting it to a pointer in out C++ glue code. By-value returns would need to be caught and stored in a new allocated pointer. By value args can just be defererenced with *. I don't think we'd need any new infra on the Dart side.
