See for details: https://fb.quip.com/QRtJAin66lPN
We need to model optional types explicitly, mostly for schema inference. So we cannot pass a `Tensor?[]` as `ArrayRef<Tensor>`, instead we need to pass it as an optional type. This PR changes it to `torch::List<c10::optional<Tensor>>`. It also makes the ops c10-full that were blocked by this.
## Backwards Compatibility
- This should not break the Python API because the representation in Python is the same and python_arg_parser just transforms the python list into a `List<optional<Tensor>>` instead of into a `List<Tensor>`.
- This should not break serialized models because there's some logic that allows loading a serialized `List<Tensor>` as `List<optional<Tensor>>`, see https://github.com/pytorch/pytorch/pull/49138/files#diff-9315f5dd045f47114c677174dcaa2f982721233eee1aa19068a42ff3ef775315R57
- This will break backwards compatibility for the C++ API. There is no implicit conversion from `ArrayRef<Tensor>` (which was the old argument type) to `List<optional<Tensor>>`. One common call pattern is `tensor.index({indices_tensor})`, where indices_tensor is another `Tensor`, and that will continue working because the `{}` initializer_list constructor for `List<optional<Tensor>>` can take `Tensor` elements that are implicitly converted to `optional<Tensor>`, but another common call pattern was `tensor.index(indices_tensor)`, where previously, the `Tensor` got implicitly converted to an `ArrayRef<Tensor>`, and to implicitly convert `Tensor -> optional<Tensor> -> List<optional<Tensor>>` would be two implicit conversions. C++ doesn't allow chaining. two implicit conversions. So those call sites have to be rewritten to `tensor.index({indices_tensor})`.

## Benchmarks (C++ instruction counts):
### Forward
#### Script
```py
from torch.utils.benchmark import Timer
counts = Timer(
stmt="""
auto t = {{op call to measure}};
""",
setup="""
using namespace torch::indexing;
auto x = torch::ones({4, 4, 4});
""",
language="cpp",
).collect_callgrind(number=1_000)
print(counts)
```
#### Results

### Autograd
#### Script
```py
from torch.utils.benchmark import Timer
counts = Timer(
stmt="""
auto t = {{op call to measure}};
""",
setup="""
using namespace torch::indexing;
auto x = torch::ones({4, 4, 4}, torch::requires_grad());
""",
language="cpp",
).collect_callgrind(number=1_000)
print(counts)
```
Note: the script measures the **forward** path of an op call with autograd enabled (i.e. calls into VariableType). It does not measure the backward path.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/36984
Follow LOG(WARNING) format for c++ side warnings in order to play well with larger services, especially when using glog. I need to hook up into GLOG internals a bit in order to override FILE/LINE without having to change the whole thing to be macros, but it seems to be stable between glog versions.
Note, this also changes caffe2_log_level to warning by default - I think it's a much better default when compiling without glog (or maybe even have info).
With glog output, stderr capture doesn't work any more in tests. That's why we instead use c10-level warnings capture.
Test Plan:
Run unittest in both glog and non-glog build mode:
glog:
```
W0416 12:06:49.778215 3311666 exception_test.cpp:23] Warning: I'm a warning (function TestBody)
```
no-glog:
```
[W exception_test.cpp:23] Warning: I'm a warning (function TestBody)
```

Summary:
The init-list form of `at::indexing::Slice` (i.e. `tensor.index({{1, None, 2}, ...})` instead of `tensor.index({Slice(1, None, 2), ...})`) in C++ API can be easily confused with the list-form indexing in Python API (e.g. `tensor[[1, 3, 2], ...]`), which is not good from readability perspective. This PR removes the init-list form of `at::indexing::Slice` to make the API less confusing.

Summary:
This PR adds the following items:
- **1st item**: `ArrayRef<TensorIndex>` and `std::initializer_list<TensorIndex>` overloads for `Tensor::index` and `Tensor::index_put_`, to be used specifically for multi-dim indexing purpose.
Design rationale:
* C++ `Tensor::index` and `Tensor::index_put_` are both existing tensor APIs, and they currently (before this PR) only accept a list of tensors (i.e. `ArrayRef<Tensor>`) as indices. If we change their signatures to also accept non-tensors as indices (i.e. `ArrayRef<TensorIndex>`, and `TensorIndex` is convertible from `Tensor` / `Slice` / `None` / `Ellipsis`), it would slow down the original code path (since now it has to go through more steps), which is undesirable.
To get around this problem, the proposed solution is to keep the original `ArrayRef<Tensor>` overload, and add `ArrayRef<TensorIndex>` and `std::initializer_list<TensorIndex>` overloads to `Tensor::index` and `Tensor::index_put_`. This way, the original code path won’t be affected, and the tensor multi-dim indexing API is only used when the user explicitly pass an `ArrayRef<TensorIndex>` or a braced-init-list of `TensorIndex`-convertible types to `Tensor::index` and `Tensor::index_put_` .
Note that the above proposed solution would still affect perf for the user’s original `Tensor::index` or `Tensor::index_put_` call sites that use a braced-init-list of tensors as input, e.g. `tensor.index({...})` or `tensor.index_put_({...}, value)`, since now such function calls would take the multi-dim indexing path instead of the original advanced indexing path. However, there are only two instances of this in our codebase (one in ATen cpp test, one in a C++ API nn init function), and they can be easily changed to explicitly use `ArrayRef<Tensor>` as input (I changed them in this PR). For external user’s code, since this is part of the C++ frontend which is still considered experimental, we will only talk about this change in the release note, and ask users to switch to using `ArrayRef<Tensor>` explicitly if they want to keep using the original advanced indexing code path.
- **2nd item**: Mechanisms for parsing `ArrayRef<TensorIndex>` indices and performing indexing operations (mirroring the functions in `torch/csrc/autograd/python_variable_indexing.cpp`).
- **3rd item**: Simple tests to demonstrate that the `Tensor::index()` and `Tensor::index_put_()` APIs work. I will add more tests after the first few PRs are reviewed.
- **4th item**: Merge Python/C++ indexing code paths, for code simplicity. I tested locally and found that there is no perf regression resulting from the merge. I will get more concrete numbers for common use cases when we settle on the overall design.

`at::indexing::TensorIndex` is used for converting C++ tensor indices such as `{None, "...", Ellipsis, 0, true, {1, None, 2}, torch::tensor({1, 2})}` into its equivalent `std::vector<TensorIndex>`, so that further tensor indexing operations can be performed using the supplied indices.
