internal/memoize: add a final argument to Bind for cleaning up

With its memoization and refcounting, the cache is well suited to the
sharing of other expensive resources, specifically those that interact
with the file system. However, it provides no means to clean up those
resources when they are no longer needed.

Add an additional argument to Bind to clean up any values produced by
the bound function when they are no longer referenced.

For golang/go#41836
