feat: WF.GuessLex: If there is only one plausible measure, use it (#2954) 
If here is only one plausible measure, there is no point having the
`GuessLex` code see if it
is terminating, running all the tactics, only for the `MkFix` code then
run the tactics again.

So if there is only one plausible measure (non-mutual recursion with
only one varying
parameter), just use that measure.

Side benefit: If the function isn’t terminating, more detailed error
messages are shown
(failing proof goals), located at the recursive calls.
