Summary:
Currently, `keep_initializers_as_input` argument in `torch.onnx.export` API can be used to choose whether to export an ONNX model with IR v3 or v4 semantics. Currently, the implementation does not check for which opset is being used for export. This is an issue because ONNX IR v4 is valid only for opset 9 and above (as listed [here](https://github.com/onnx/onnx/releases/tag/v1.4.0)), and opset 8 or lower export with `keep_initializers_as_input=False` will create a illegal ONNX graph.
This change fixes this by introducing a check on opset version when deciding whether to export ONNX IR v3 or v4.

Summary:
Currently ONNX constant folding (`do_constant_folding=True` arg in `torch.onnx.export` API) supports only opset 9 and 10 of ONNX. Opset 11 support was recently introduced in the ONNX exporter. For opset 11, it is currently a no-op. This change enables ONNX constant folding for opset 11. Specifically there are three main changes:
1) Turn on constant folding ONNX pass for opset 11.
2) Enable constant folding tests in `test/onnx/test_utility_funs.py` and `test/onnx/test_pytorch_onnx_onnxruntime.py` for opset 11.

There is no reason to have it in a general API of Module/Method - it's
just another graph pass. It was there because some time ago modules were
not first class and all graphs were lowered. After that changed, this
API was added for easier transition, but now we don't need it anymore.

Summary:
We currently support exporting traced interpolate ops to ONNX.
Scripting interpolate op invokes aten::__interpolate in the Torch IR (instead of aten::upsample_[mode][dim]d), which we do not support yet.
This PR implements the ONNX symbolic for __interpolate() to support exporting interpolate in scripting scenarios.

Summary:
ONNX does not support dictionaries for inputs and output. The reason is that the arg flattening and unflattening does not handle Dictionary types.
This PR adds flattening/unflattening support for dictionaries and strings.
However this feature should be handled with caution for input dictionaries; and users need to verify their dict inputs carefully, and keep in mind that dynamic lookups are not available.
This PR will allow exporting cases where models have dictionnary outputs (detection and segmentation models in torchvision), and where dictionary inputs are used for model configurations (MultiScaleRoiAlign in torchvision).

Summary:
This is a follow-up PR for https://github.com/pytorch/pytorch/pull/23284. In that PR we had removed changing the default behavior for `keep_initializers_as_input` argument to the export API. With this PR we are enabling that change in that if `keep_initializers_as_input` is not specified then value/behavior for this argument is chosen automatically depending on whether the export type is ONNX or not.
This was part of the earlier PR was removed for further review. The test points have also been updated.
This change may fail some internal tests which may require explicitly setting `keep_initializers_as_input=True` to preserve old behavior.

The way it is implemented currently is bad because while we're inlining
to a graph G, we are also mutating all the graphs that are being
inlined. The problem is that the graphs we're inlining are usually the
original graphs of functions, so we're silently changing them behind the
scenes, and we don't have a way to recover 'unoptimized' graphs
afterwards.

Before, we inlined as part of the initial IR generation process, which
has a few disadvantages:
1. It loses information about what nodes came from which function/method
calls. Other parties who want to implement transformations on the
function/module level don't have a reliable way of doing so.
2. It duplicates a ton of code if we are inlining the same
function/method a tons of times.
After this PR: inline is deferred to the optimization stage, so
optimizations that rely on inlining will still work. But things get
serialized with the function/method calls in.

Summary:
Starting ONNX IR version 4, the initializers in the ONNX graph do not have to be inputs of the graphs. This constraint, which existed in IR version 3 and earlier, was relaxed in IR version 4. This PR provides an API level argument to allow ONNX export with the relaxed constraint of IR version 4, i.e. provides the option to not include initializers as inputs. This allows backends/runtimes to do certain optimizations, such as constant folding, better.
*Edit*: After discussion with houseroad we have the following behavior. For any OperatorExportType, except OperatorExportTypes.ONNX, the current status of export is maintained in this PR by default. However, the user can override it by setting the `keep_initializers_as_inputs` argument to the export API. But when exporting to ONNX, i.e. OperatorExportType is OperatorExportTypes.ONNX, the current status is changed in that by default the initializers are NOT part of the input. Again, the default can be overridden by setting the `keep_initializers_as_inputs` argument.

Dead code elimination assumes a valid jit graph because it checks if operators have side effects.
The onnx export path destroys the jit graph right before calling dead code elimination, but it actually doesn't care about side effects.
We can just call dead code elimination and disable side effect lookup and things should work.

Summary:
- [x] Add tests after https://github.com/pytorch/pytorch/pull/20256 is merged
- Support exporting ScriptModule with inputs/outputs of arbitrarily constructed tuples.
- Moved the assigning of output shapes to after graph conversion to ONNX is completed. By then all tuples in the IR has already been lowered by the pass ```_jit_pass_lower_all_tuples```. If assigning output shapes is required to happen before that, we'll need to hand parse the tuple structures in the graph, and repeat the same logic in ```_jit_pass_lower_all_tuples```. Handling inputs is easier because all tuple information is encoded within the input tensor type.
- Swap the order of ```_jit_pass_lower_all_tuples``` and ```_jit_pass_erase_number_types```. Ops like ```prim::TupleIndex``` relies on index being a scalar. ```_jit_pass_erase_number_types``` will convert these kind of scalars to tensors.

* **#18598 Turn on F401: Unused import warning.**
This was requested by someone at Facebook; this lint is turned
on for Facebook by default. "Sure, why not."
I had to noqa a number of imports in __init__. Hypothetically
we're supposed to use __all__ in this case, but I was too lazy
to fix it. Left for future work.
Be careful! flake8-2 and flake8-3 behave differently with
respect to import resolution for # type: comments. flake8-3 will
report an import unused; flake8-2 will not. For now, I just
noqa'd all these sites.
All the changes were done by hand.
