* Update preview1 to trap on misaligned pointers Previously Wasmtime would return `EINVAL` to a guest but the upstream documentation indicates that misaligned pointers should trap, so this commit updates the alignment error to get converted into a trap rather than than being returned to the guest. * Change OOB errors to traps too * Update preview2's implementation of preview1 * Handle some more errors
