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
