* Fix with `WOLFSSL_ALT_CERT_CHAINS` to resolve issue with using a trusted intermediate to validate a partial chain. With the alt cert chain enabled a CA may fail with only `ASN_NO_SIGNER_E` and the connection is allowed if the peer's certificate validates to a trusted CA. Eliminates overly complex 1 deep error alternate chain detection logic. Resolves ZD 4525.
* Refactor and cleanup of ProcessPeerPerts to combine duplicate code and improve code commenting.
* Fix for CA path len check in `ParseCertRelative` to always check for self-signed case (was previously only in NO_SKID case).
* Improvement to include self-signed flag in the DecodedCert struct.
