We are adding more actions to convert the raw inputs and label. 1. The new CP can do the input/label/BlockMask sharding this in this method. 2. The experimental full dtensor model can simply override this method without changing too many Trainer code. This method is extracted from #1857 Makeing this a standalone PR allows us to continue the two projects above without one blocks another. ghstack-source-id: d1882a7 Pull-Request: #1985
