Original change's description:
> [wasm] Consolidate function table representation.
>
> This CL avoids the need to reference the function tables (and signatures)
> as either fixed arrays or vectors, preferring vectors.
>
> The only place we need fixed arrays is on the compiled module, to support
> serialization. When we move off the GC heap, we'll also move away
> from fixed arrays in that last case.
>
> The CL aids with getting wasm of the GC heap, by reducing the places
> and representations we'll need to change when changing the way we
> reference fixed tables.
