Fix #47728: Add missing openssl constants

This adds PKCS7_NOSMIMECAP, PKCS7_CRLFEOL, PKCS7_NOCRL and
PKCS7_NO_DUAL_CONTENT constants. They might be potentially useful
in some scenarious.

Test is not added as it is not clear if there is much need for those and
it would require much bigger effort just to test OpenSSL functionality.

Closes GH-19450
