Simplify arity errors, rewording spread errors (#43855)
* Scribbles + tests

The second test actually requires node types

* Basically working

The two simple fixes, in arity error reporting, are in, and the
simplification of arity error reporting is half-done. I haven't started
on any improvements to call assignability.

* trim out too-real test case

* Finish cleanup

And reword error a little.

* Simplify and reword spread errors

* handle spreads first

* update baselines

* Address PR comments
