Move CompositeCompliance tests to their own TestCase (#74644)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/74644
This is in preparation for me adding additional tests for:
1. composite compliance of autograd formulas
2. composite compliance of forward-mode AD formulas
This PR also changes these tests to run on both CPU and CUDA. Previously
they were just run on CPU, but it turns out there's a lot of branching
on the device in composite operations in PyTorch today :/
Test Plan: - wait for tests
