The fusion stuff is pretty hard to debug. Given that we're not shipping this part of the stack any time soon, let's temporarily disable them and re-enable them when somebody has the cycles to debug them.
Test Plan: Verified that the tests are now disabled

Constructor logic was spread throughout InferenceModule and StaticRuntime. This diff unifies the two. After a lot of discussion on this diff D25961626 it became apparent that `clone` is uglier than a cheap StaticRuntime.
This means StaticRuntime is effectively StaticModule and the only code in the new StaticRuntime is the `run` functions.
```
graph, schema = PrepareForStaticModule(torchscript_module)
sm = StaticModule(graph, schema, options)
sm(inputs)
// or create many cheap runtimes with the module
sr = StaticRuntime(sm)
sr(inputs)
```
Changelist:
- Rename InferenceModule StaticModule
- Move all logic for construction into StaticModule
- Create a new StaticRuntime that only has a unique memory planner (everything else is in StaticModule)
- Update comments with explanation
- Propagate all changes to predictor integration
- Propagate all changes to python integration
- Change semantics to be a bit more PyTorch-standard (no "run" calls, no "get_" getters).

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/46896
The idea of the memory model is quite similar to that of BlackBoxPredictor, however, it's more complicated in pt due to 1) tensor views that share storage with storage refcount bumps but with different TensorImpls, 2) tensors sharing the same TensorImpl and the same storage, but with no refcount bump of the StorageImpl, 3) data types such as TensorList and Tuples that have Tensors in them, 4) need to support non-out/out variant mix while we move the aten ops to out variants.
As a result, I have to make the following adjustments:
1) remove tensors in output Tuples from internal blob list;
2) for memory allocation/deallocation, get candidate Tensors from the outputs of ops with out variant, extract StorageImpls from the Tensors, dedup, and remove output tensor StorageImpls, and get the final list of blobs for memory planning;
3) during the clean_up_memory pass, clean up memory held by the StorageImpls as well as Tensors/Lists/Tuples in IValues that don't participate in memory planning to reduce overall memory usage
Risk:
PyTorch team is planning to deprecate the current resize_outout api, which we do rely on. This is a pretty big risk.

`StaticRuntime::run_individual` is to mimic the caffe2 operator benchmark `SimpleNet::TEST_Benchmark`, so we can accurate information on the operator breakdown. We found that the PyTorch AutogradProfiler adds a lot of overhead to small models, such as the adindexer precomputation_merge net, 100% for batch_size 1, 33% for batch_size 20. This implementation adds very little overhead, as shown in the test plan.
Test Plan: Test results are fb internal only.

Nothing fancy, just a basic implementation of the graph executor without using stack machine.

Summary:
This PR whitelists and simplifies graphs to help with development later on. Key to note in this PR is the use of both a pattern substitution and the registration of custom operators. This will likely be one of the main optimization types done in this folder.

Summary:
The premise of this approach is that a small subset of neural networks are well represented by a data flow graph. The README contains more information.
The name is subject to change, but I thought it was a cute reference to fire.
suo let me know if you'd prefer this in a different spot. Since it lowers a JIT'd module directly I assumed the JIT folder would be appropriate. There is no exposed Python interface yet (but is mocked up in `test_accelerant.py`)
