The actor compiler does not handle this correctly, so disallow it for
now. We could probably support this someday if someone is sufficiently
motivated.
Previously this would miscompile and hopefully cause some kind of syntax
error in the generated code. Now it issues a helpful diagnostic.
Tested by adding an actor with a state variable that tries to use
uniform initialization syntax and observing the error message looks
good. We don't have any infrastructure for testing that the
ActorCompiler rejects something, so I'm not including a test in this
change. We could probably add that relatively easily though.
We had been disabling -Wdelete-non-virtual-dtor, because this seems to be done intentionally in the generated code of the actor compiler. I spent some time trying to rewrite it in a way that doesn't literally delete/destroy through a pointer to a base class without a virtual destructor, but I was unable to come up with something that passes correctness. My best guess is that we do this so that we can destroy actor state classes, call callbacks registered on the actor SAV, and then destroy the SAV.
Anyway now we'll detect new usages of deleting through a pointer to a base class without a virtual destructor.
