Create explicit cmTarget::FinishConfigure step

This method is called during ConfigureFinalPass on every target.  It
gives each target a chance to do some final processing after it is known
that no more commands will affect it.  Currently we just call the old
AnalyzeLibDependencies that used to be called directly.
