gradcheck (#14596)

Summary:
- allow gradcheck to take sparse tensor as input
- sparse output is not allowed yet at gradcheck
- add backward for `to_dense()` to get around sparse output
- calling gradcheck at test_sparse, so that we can use `_gen_sparse()` and also easily cover coalesced / uncoalesced test cases
