dynamo + torchdeploy bug

[PaliC]

Stack from ghstack (oldest at bottom):

• -> #265

I ran into a few bugs when trying to use deploy + dynamo. This PR adds some torchdynamo unit tests to create a minimal repro for these bugs. So far there are 2 bugs

1. Outputs of using dynamo + torchscript + deploy is inconsistent with using just torchscript.
2. Multithreading models which use dynamo run into errors with prims.

The output of building and running test_deploy_compat.cpp (which contain single and multithreaded dynamo+torchscript+deploy tests using resnet) are here.

One can run these tests again by running

cd multipy
python multipy/runtime/example/generate_examples.py
python -m pip install -e .
./multipy/runtime/build/test_deploy_compat
