Define 'multiplicity' for cyclic dependencies
We create target property "LINK_INTERFACE_MULTIPLICITY" and a per-config version "LINK_INTERFACE_MULTIPLICITY_<CONFIG>". It sets the number of times a linker should scan through a mutually dependent group of static libraries. The largest value of this property on any target in the group is used. This will help projects link even for extreme cases of cyclic inter-target dependencies.
