ENH: Use improved target dependencies for Xcode 

In cmGlobalGenerator we use cmComputeTargetDepends to construct a safe,
non-circular set of inter-target dependencies.  This change enables use
of the results by the Xcode generator.  It also removes a lot of old
code and another use of the old-style linking logic.  See issue #7652.
