Add support for resources

[afsalthaj]

There was lot of complexities when it used to work with golem, which doesn't need to exist, when trying to make it directly work with wasmtime. This PR is making sure wasmtime can use rib and make sure all resource method invokes work nicely using repl

wasmtime on  wasmtime_rib !?❯ target/debug/wasmtime repl ../rib-smoke/target/wasm32-wasip1/debug/rib_smoke.wasm
>>>
>>> let x = instance()
()
>>> let r = x.cart("foo")
()
>>> r.add-line({sku: "foo", qty: 42})
()
>>> r.line-count()
1
>>> r.add-line({sku: "foo", qty: 42})
()
>>> r.line-count()
2
>>>

There are a few rough edges at host side. I think that needs to be fixed with a few clean ups
