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".

The StructProxy::Create() used the static type information to inspect
the value. However, for abstract references like anyref, dataref, ...
this does not contain the required struct_index.
To fix this the WasmTypeInfo stores the type_index for structs and
arrays.
