SI-8040 Warn unused parameters
One can `-Ywarn-unused:params` or more narrowly warn only for
unused implicit parameters with `-Ywarn-unused:implicits`.
Params includes constructor parameters.
The settings for privates and locals are not yet distinguished.
```
$ skalac -Ywarn-unused:help
Enable or disable specific `unused' warnings
imports Warn if an import selector is not referenced.
patvars Warn if a variable bound in a pattern is unused.
privates Warn if a private member is unused.
locals Warn if a local definition is unused.
params Warn if a value parameter is unused.
implicits Warn if an implicit parameter is unused.
```
