Wanchao Liang 0524b2829a [shard] Add ReplicatedTensor (#73529) 
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73529

Add ReplicatedTensor, a ReplicatedTensor is a type of tensor that have the same value on all ranks across the world_size.

ReplicatedTensor is a :class:`~torch.Tensor` subclass, and it could be used together with ShardedTensor/Tensor together to express different types of computation. The inter-op rules defined as (using torch.add as an example op):
    ReplicatedTensor + ReplicatedTensor = ReplicatedTensor
    ReplicatedTensor + torch.Tensor = torch.Tensor
    ReplicatedTensor + ShardedTensor = ShardedTensor

We also added a `validate()` API to help user validate if a replicated tensor on certain process_group is truly replicated or not.

TODO: next PR gonna add ShardedTensor/PartialTensor logic to handle ReplicatedTensor.

This function is used to determine the indices when slicing the list of selected tests when
``options.first``(:attr:`find_last_index`=False) and/or ``options.last``(:attr:`find_last_index`=True) are used.
:attr:`selected_tests` can be a list that contains multiple consequent occurrences of tests
as part of the same test module, e.g.:
```
selected_tests = ['autograd', 'cuda', **'torch.TestTorch.test_acos',
'torch.TestTorch.test_tan', 'torch.TestTorch.test_add'**, 'utils']
```
If :attr:`test`='torch' and :attr:`find_last_index`=False, result should be **2**.
If :attr:`test`='torch' and :attr:`find_last_index`=True, result should be **4**.
Args:
test (str): Name of test to lookup
selected_tests (list): List of tests
find_last_index (bool, optional): should we lookup the index of first or last
occurrence (first is default)
Returns:
