openssl_*: improve passphrase handling for private keys in PyOpenSSL (#53489)

* Raise OpenSSLBadPassphraseError if passphrase is wrong.

* Improve handling of passphrase errors.

Current behavior for modules is: if passphrase is wrong (or wrongly specified), fail.
Current behavior for openssl_privatekey is: if passphrase is worng (or wrongly specified), regenerate.

* Add changelog.

* Add tests.

* Adjustments for some versions of PyOpenSSL.

* Update lib/ansible/modules/crypto/openssl_certificate.py

Improve text.
