Matt Caswell 7a949ae5f1 Don't ask for an invalid group in an HRR
If the client sends us a group in a key_share that is in our
supported_groups list but is otherwise not suitable (e.g. not compatible
with TLSv1.3) we reject it. We should not ask for that same group again
in a subsequent HRR.

Fixes #21157
