Roland Shoemaker afb105056d crypto/x509: make sure pub key is non-nil before interface conversion
alreadyInChain assumes all keys fit a interface which contains the
Equal method (which they do), but this ignores that certificates may
have a nil key when PublicKeyAlgorithm is UnknownPublicKeyAlgorithm. In
this case alreadyInChain panics.

Check that the key is non-nil as part of considerCandidate (we are never
going to build a chain containing UnknownPublicKeyAlgorithm anyway).

Fixes #65390
Fixes CVE-2024-24783
