This change also modifies the way references are typed: Instead of
using the static type (which may be a generic type like anyref) the
actual type based on the referenced object is used.
While this is very useful for arrays and structs (and somewhat nice for
i31 not just being a number but also having some type information), it
means for non-null values that the reference type is "not nullable",
so it will show e.g. "ref $type0" although the static type might be
"ref null $type0".

This is a left-over of the removal of the dynamic (rtt-based)
variants.

Also fix eqref/i31ref fromJS() handling to accept unwrapped Smis.
This does not convert HeapNumbers to Smis if they fit.

which packs wasm objects into JS objects if the js-interop flag is not set.
This is the counterpart to extern.internalize introduced in
