The problem was that an equation in `split` had two guards (one about
visiblity and one about `n_req`). So it fell thorugh if /either/
was False. But the next equation then assumed an invisible binder.
Simple bug, easily fixed. Fixes #25661.

This commit generalises the infrastructure used for diagnostic codes,
allowing it to be used for other namespaces than the GHC namespace.
In particular, this enables GHCi to re-use the same infrastructure to
emit error messages.

This patch creates the 'GhciCommandErrorMessage' data type which
implents the 'Diagnostic' class and also provides error code for these
error conditions.
