Add GUC checks for ssl_min_protocol_version and ssl_max_protocol_version
Mixing incorrect bounds set in the SSL context leads to confusing error
messages generated by OpenSSL which are hard to act on. New checks are
added within the GUC machinery to improve the user experience as they
apply to any SSL implementation, not only OpenSSL, and doing the checks
beforehand avoids the creation of a SSL during a reload (or startup)
which we know will never be used anyway.
Backpatch down to 12, as those parameters have been introduced by
e73e67c.
