Peter Goldsborough 03d0a70a4d Set random seed at the start of C++ tests (#8903)
Summary:
Sets the random seed at the start of C++ tests so that everything is super deterministic.

I made sure we only generate random values from torch instead of `std::`, so that this seed always applies. I.e. I do:

```
torch::randint(2, {2}, at::kInt64)
```

instead of

```
std::rand() % 2
```

Also got rid of the tests that test the random seeding, since it would interfere here. And the test is not useful since we just use ATen's seeding mechanism, which should work.

Fixes  #7288 #7286 #7289

C++ API Tests

In this folder live the tests for PyTorch's C++ API (formerly known as autogradpp). They use the Catch2 test framework.

CUDA Tests

The way we handle CUDA tests is by separating them into a separate TEST_CASE (e.g. we have optim and optim_cuda test cases in optim.cpp), and giving them the [cuda] tag. Then, inside main.cpp we detect at runtime whether CUDA is available. If not, we disable these CUDA tests by appending ~[cuda] to the test specifications. The ~ disables the tag.

One annoying aspect is that Catch only allows filtering on test cases and not sections. Ideally, one could have a section like LSTM inside the RNN test case, and give this section a [cuda] tag to only run it when CUDA is available. Instead, we have to create a whole separate RNN_cuda test case and put all these CUDA sections in there.

Integration Tests

Integration tests use the MNIST dataset. You must download it by running the following command from the PyTorch root folder:

$ python tools/download_mnist.py -d test/cpp/api/mnist
