Instead of modeling array initialization as a thin wrapper around tuple initialization, handle it like a function call, with a return slot as part of its input. This better matches how initialization via a call to `ImplicitAs::Convert` will eventually work, and in particular lets us do in-place initialization of arrays rather than always creating a temporary.
