Track new configure flags introduced for version 11 in pg_config.h.win32

Enterprise / PostgreSQL - Michael Paquier [paquier.xyz] - 19 June 2018 00:00 EDT

The following set of flags mainly matter when building Postgres code with MSVC and those have been forgotten with latest developments:
- HAVE_LDAP_INITIALIZE, added by 35c0754f, and marked as disabled. ldap_initialize() is a non-standard extension that provides a way to use "ldaps" with OpenLDAP, but it is not supported on Windows, and instead the non-standard ldap_sslinit() is used if WIN32 is defined. Per input from Thomas Munro.- HAVE_X509_GET_SIGNATURE_NID, added by 054e8c6c, which is used by SCRAM's channel binding tls-server-end-point. Having this flag disabled would cause this channel binding type to be unsupported for Windows builds.- HAVE_SSL_CLEAR_OPTIONS, added recently as of a364dfa4 to disable SSL compression.- HAVE_ASN1_STRING_GET0_DATA, added by 5c6df67, which is used to track a new compatibility with OpenSSL 1.1.0. This was missing from pg_config.win32.h and is not enabled by default. HAVE_BIO_GET_DATA, HAVE_OPENSSL_INIT_SSL and HAVE_BIO_METH_NEW gain the same treatment.

The second and third flags are enabled with this commit, which raises the bar of OpenSSL support to 1.0.2 on Windows as a minimum. As this is the LTS (long-time support) version of OpenSSL community and knowing that all recent installers referred by OpenSSL upstream don't have anymore 1.0.1 or older, we could live with that requirement. In order to allow the code to compile with OpenSSL 1.1.0, all the flags mentioned above need to be enabled in pg_config.h.win32.
