Updating version file to reflect that 12.16 has been branched.

Updating to 12.17 for now because in Trilinos 13 we are going
to break backward compatibility and don't want to do so quite yet.
Also, we are planning to change the versioning approach. This change
does not indicate we are planning a 12.18 release.
