León Orell Valerian Liehr 618c15eb6c Reject const projections behind trait aliases that mention Self ...

This fully rewords the diagnostic that was previously only emitted for assoc ty bindings.
That's because it incorrectly called trait aliases *type aliases* and didn't really
make it clear what the root cause is.

The added test used to ICE prior to this change.

I've double-checked that the preexisting test I've modified still ICEs in
nightly-2025-03-29.
