Drop support for OpenSSL < 1.1.0 on Windows

PR php#13498 bumped the required OpenSSL version to 1.1.1, but apparently
only for non Windows system.  We catch up somewhat by dropping support
for OpenSSL < 1.1.0 on Windows; besides completely removing detection
of old OpenSSL versions in `SETUP_OPENSSL`, we also ensure that all
bundled extension using this function do no longer accept OpenSSL <
1.1.0, to avoid to still be able to build these extensions with older
`phpize` scripts.

We do not cater to `--phar-native-ssl` yet; that might better be
addressed by php#14578.
