Path quality profile sharing for GLB multi-link support on IP Fabric

While we support larger CLOS networks and more GPUs, the TH5 chipset can only support 64 profiles. In CLOS networks with five or more stages, some nodes, like super spines exceed 64 next-next-hop nodes. We can reuse the profiles under specific conditions to support more than 64 next-next-hop nodes. We support GLB for CLOS networks with profile sharing in hyperscaler artificial intelligence/machine learning (AI/ML) fabrics containing tens of thousands of leaves or GPUs.
