Unsupport GlobalStep in subclass of ValuePtrBase

[Lihengwannafly]

When we save checkpoint, the error F ./tensorflow/core/framework/embedding/value_ptr.h:256] Unsupport GlobalStep in subclass of ValuePtrBase occurs. Because I find that the checkpoint is a temporary file best_checkpoint/best.data-00000-of-00001.tempstate11898667549733680686.

Whether you a model from a model with global_step in EmbeddingVariable, but there's no such configure in graph.

I found that the feature eviction is triggered when saving checkpoint,.Therefore, I try to enable GlobalStepEvict for all embedding variables, and it works. So, is it necessary to enable GlobalStepEvict for all embedding variables?

It is possible to be a compilation environment, and there is no problem with the official mirror.
