(ITS#7979) mozNSS does not process TLS_PROTOCOL_MIN

Currently there is no check for TLS_PROTOCOL_MIN in the mozNSS code. mozNSS
defaults to SSLv3/TLS1.0 which is no longer considered secure. If a client only
supports TLSv1.1 and up, the openldap ldapsearch will fail to connect over SSL.
ldapsearch -H "ldaps://localhost.localdomain:636" -b "" -s base objectclass=*
LDAPTLS_PROTOCOL_MIN=3.2 ldapsearch -H "ldaps://localhost.localdomain:636" -b ""
-s base objectclass=*
The fix is to grab the supported version range from NSS, adjust the minimum
range if TLS_PROTOCOL_MIN is set, and then set the NSS default range with the
min and max versions.
Also updated the NSS version string map table to support up to TLSv1.3
