Allow multiple values per key in name fields in openssl_certificate/csr (#30338)

* allow multiple values per key in name fields in openssl_certificate

* check correct side of comparison

* trigger only on lists

* add subject parameter to openssl_csr

* fix key: value mapping not skipping None elements

* temporary fix for undefined "subject" field

* fix iteration over subject entries

* fix docs

* quote sample string

* allow csr with only subject defined

* fix integration test

* look up NIDs before comparing, add hidden _strict params

* deal with empty issuer/subject fields

* adapt integration tests

* also normalize output from pyopenssl

* fix issue with _sanitize_inputs

* don't convert empty lists

* workaround for pyopenssl limitations

* properly encode the input to the txt2nid function

* another to_bytes fix

* make subject, commonname and subjecAltName completely optional

* don't compare hashes of keys in openssl_csr integration tests

* add integration test for old API in openssl_csr

* compare keys directly in certificate and publickey integration tests

* fix typo
