v8.serialize() currently rejects X509Certificate objects. Add a host object encoding containing the certificate's DER snapshot, including its issuerCertificate chain, and reconstruct fresh X509Certificate objects in v8.deserialize().

Read the stored snapshot rather than the cached raw Buffer, which can be modified by callers. Decode each certificate independently without imposing issuer relationships on the serialized sequence.

This is PR 3 out of 4 in an X.509 series addressing #48730 and #51169. (it can land independently of PR 2 https://github.com/proxy/redirect.github.com/nodejs/node/pull/67082)
