Georg Schmid b1db8d847f [torque] Infer type arguments of generic struct initializers
Previously when creating a new generic struct, one had to explicitly provide all type arguments, e.g., for the generic struct

  struct Box<T: type> {
    const value: T;
  }

one would initialize a new box using

  const aSmi: Smi = ...;
  const box = Box<Smi> { value: aSmi };

With the additions in this CL the explicit type argument can be omitted. Type inference proceeds analogously to specialization of generic callables.

Additionally, this CL slightly refactors class and struct initialization, and make type inference more permissive in the presence of unsupported type constructors (concretely, union types and function types).
