Port legacy all(*) to ATen (#15540)

Port legacy all(*) to ATen (#15540)

Summary:
Questions:

1. ~This PR disables `common_dtype` computation [in `TensorIterator.cpp`](https://github.com/mrshenli/pytorch/blob/all/aten/src/ATen/native/TensorIterator.cpp#L489-L491) for `all*` operators. The reason is that, [this code](https://github.com/mrshenli/pytorch/blob/all/aten/src/ATen/native/TensorIterator.cpp#L120) otherwise complains type mismatch, where the `op.tensor` is `type Variable[CPUByteType]` while the `op` is `CPUByteType`. I am not sure if this is the right solution for this problem.~

2. Should I clean up all occurrences of `_th_all` and `_th_all_out` (and `logicalAnd`, `logicalAndAll`)?

3. Do I need to implement derivatives for `all`?
