This is a reland of commit 936b61a209
Change compared to original: Fix parameter types for CallRuntimeStub
in Liftoff.
Original change's description:
> [wasm-gc] Canonicalize JS Numbers as i31ref at the boundary
>
> JS numbers flowing into Wasm as i31ref should be canonicalized at the
> boundary. In-range numbers get canonicalized to Smis, and out-of-range
> numbers to HeapNumbers. This way, casting to i31ref, or checking for
> i31ref when casting to other types, is reduced to a Smi check.
