VS: Generate a custom command only in the least dependent target
If a custom command is assigned to multiple targets, generate the build
rule only in the least-dependent `.vcxproj` file. Otherwise MSBuild
will run the command on the first build of a dependent target even if
its dependencies already brought the command up to date (in order to
populates its build log).
Generate targets in least-to-most-dependent order, and assign a custom
command to the least dependent target.
Added cmLocalVisualStudio10Generator::GenerateTargetsDepthFirst to call
cmVisualStudio10TargetGenerator::Generate in least-dependent order.
Moved SourcesVisited from cmVisualStudio10TargetGenerator to
cmLocalVisualStudio10Generator to avoid attaching a custom command to
multiple targets among the local generator.
Fixes: #16767
