Avoid duplicate ZERO_CHECK in VS solutions

The commit "Avoid non-root copies of root-only targets" moved the check
for root-only targets into cmGlobalGenerator::GetTargetSets to avoid
adding multiple ALL_BUILD targets to the "original" target set.  This
approach did not work for ZERO_CHECK targets though because those are
pulled in by dependency analysis.

Instead we eliminate duplicate ZERO_CHECK targets altogether and refer
to a single one from all solution files.  This cleans up VS 10 project
file references to ZERO_CHECK targets anyway.
