This commit updates the various tooling used by wasmtime which has new updates to the module linking proposal. This is done primarily to sync with WebAssembly/module-linking#26. The main change implemented here is that wasmtime now supports creating instances from a set of values, nott just from instantiating a module. Additionally subtyping handling of modules with respect to imports is now properly handled by desugaring two-level imports to imports of instances. A number of small refactorings are included here as well, but most of them are in accordance with the changes to `wasmparser` and the updated binary format for module linking.
