build(Hi.WpfPlus): start the 3.2 package line and restart VersionBuild

The 3.1 line ends at Hi.WpfPlus 3.1.143 -- tag v3.1.143, part of the aligned
hinc-suite/3.1.175 set. master now produces 3.2 and VersionBuild restarts at 0,
so the first published 3.2 package is 3.2.1: IncrementPackageID.targets bumps
before the build, not after it.

The 3.1.158 stamp this replaces was a local increment from a deploy run whose
upload step is commented out, so it never reached the feed and nothing depends on
it. Fixes for customers pinned to 3.1 come off the support/3.1 branch.
