Genex: Simplify TARGET_PROPERTY transitive lookup 

In cmGeneratorExpressionEvaluator, make getLinkedTargetsContent a
template so it can traverse over either the Libraries in a cmTarget
LinkImplementationLibraries or a cmTarget LinkInterfaceLibraries.  This
also avoids creating a separate vector<cmTarget*>.
