Missing OpenSSL constants

[Girgias]

Some are in the PHP 8.4 UPGRADING guide, however more are missing and I don't have version information for them:

• X509_PURPOSE_OCSP_HELPER
• X509_PURPOSE_TIMESTAMP_SIGN
• PKCS7_DETACHED
• PKCS7_TEXT
• PKCS7_NOINTERN
• PKCS7_NOVERIFY
• PKCS7_NOCHAIN
• PKCS7_NOCERTS
• PKCS7_NOATTR
• PKCS7_BINARY
• PKCS7_NOSIGS
• PKCS7_NOOLDMIMETYPE
• OPENSSL_CMS_DETACHED
• OPENSSL_CMS_TEXT
• OPENSSL_CMS_NOINTERN
• OPENSSL_CMS_NOVERIFY
• OPENSSL_CMS_NOCERTS
• OPENSSL_CMS_NOATTR
• OPENSSL_CMS_BINARY
• OPENSSL_CMS_NOSIGS
• OPENSSL_CMS_OLDMIMETYPE
• OPENSSL_KEYTYPE_X25519
• OPENSSL_KEYTYPE_ED25519
• OPENSSL_KEYTYPE_X448
• OPENSSL_KEYTYPE_ED448

Determined via a new tool I'm working on.

Added in PHP 8.3, always available:
