Add Torch Dependency Resolution

[8W9aG]

• Use our compatibility matrix to automatically resolve the torch version if the torch version is blank but adjacent dependencies are defined.

• Make torchaudio capable of determining CUDA version compatibility like torchvision

• Rewrite dependency versions to align with resolved versions

• Remove version modifiers, this is now satisfied by adding in extra index URLs to the requirements

• Fixes: https://github.com/replicate/cog/issues/1951

Now that the tests run properly, that test_torch_version_resolution_with_torchvision test failure looks suspicious 👀

Looks like we are hitting the timeout on integration tests, I will bump to 20
