Fix linking ext/curl against OpenSSL

Following 68f6ab7, the ext/curl doesn't
need to be linked against OpenSSL anymore, if curl_version_info_data
ssl_version is OpenSSL/1.1 or later.

With OpenSSL 3 and later the old SSL crypto lock check was detected
here.

This also uses a common PHP_SETUP_OPENSSL macro for checking OpenSSL and
syncs the minimum OpenSSL version across the PHP build system.

Currently, PHP requires OpenSSL version 1.0.2 or later. Once the OpenSSL
minimum version is 1.1 or later, this check can be removed and the code
for using the crypto locking callbacks.
