As title
If one table is using feature score eviction in one tbe, then all tables in this tbe need to use the same policy. Feature score eviction can support ttl based eviction now. This diff is adding support no eviction in feature score eviction policy.

As title, `has_running_evict` and `trigger_feature_evict` are needed to support sync trigger eviction

Summary: See diff D85604160, this KVZCHEvictionTBEConfig is in FBGEMM and used in torchrec. Both FBGEEM and torchrec are open source in github. It is required to land first, otherwise torchrec github build will throw error {F1983027645}

Before KVZCH is using ID_COUNT and MEM_UTIL eviction trigger mode, both are very tricky and hard for model engineer to decide what num to use for the id count or mem util threshold. Besides that, the eviction start time is out of sync after some time in training, which can cause great qps drop during eviction. 

This diff is adding support for free memory trigger eviction. It will check how many free memory left every N batch in every rank and if free memory below the threshold, it will trigger eviction in all tbes of all ranks using all reduce. In this way, we can force the start time of eviction in all ranks.
