Enable fuzzing the module linking implementation

Browse Source 
This commit updates all the wasm-tools crates that we use and enables
fuzzing of the module linking proposal in our various fuzz targets. This
also refactors some of the dummy value generation logic to not be
fallible and to always succeed, the thinking being that we don't want to
accidentally hide errors while fuzzing. Additionally instantiation is
only allowed to fail with a `Trap`, other failure reasons are unwrapped.
