Fixes #57098.
This PR extends existing logic for checking whether a closure that
is
FnOnce
and therefore moves variables that it captures from theenvironment has already been invoked when being invoked again.
Now, this logic will also check whether the closure is being moved after
previously being moved or invoked and add an appropriate note.
