Currently, it is possible to declare macros, builtins, etc., without
specifying a return type, in which case the return type is treated as
void. This is confusing; the code is more clear if we require the return
type to be specified.
Aside from src/torque, this change is almost entirely just adding
`: void` until the compiler is happy. However, two intrinsics in
src/builtins/torque-internal.tq have been corrected to declare an
appropriate return type. Those two intrinsics were only used in code
generated within the compiler after the type-checking phase, so we never
noticed that their return types were declared incorrectly.
