Use after free passing `externref`s to Wasm in Wasmtime

Impact There was a use-after-free bug when passing externrefs from the host to guest Wasm content. To trigger the bug, you have to explicitly pass multiple externrefs from the host to a Wasm instance at the same time, either by passing multiple externrefs as arguments from host code to a Wasm...
