Fix an issue in adapter module partitioning (#4622)

When an adapter module depends on a particular core wasm instance this
means that it actually depends on not only that instance but all prior
core wasm instances as well. This is because core wasm instances must be
instantiated in the specified order within a component and that cannot
change depending on the dataflow between adapters. This commit fixes a
possible panic from linearizing the component dfg where an adapter
module tried to depend on an instance that hadn't been instantiated yet
because the ordering dependency between core wasm instances hadn't been
modeled.
