remove multiple nodes/edges types simultaneously from heterograph

## 🚀 Feature

Request from user: https://discuss.dgl.ai/t/how-to-remove-multiple-types-of-nodes-simultaneously-with-eid-stored/2366/1.
For now, https://docs.dgl.ai/en/latest/generated/dgl.remove_nodes.html#dgl.remove_nodes supports single type only. so does `remove_edges`.

## Motivation
one want to remove multiple node types simultaneously and store original nids/eids. For now, we have to remove one by one in iterations and have to keep track of original nids/eids. If we want to query real original nids/eids, just walk backward. This is a bit inconvenient.
