Summary: Modify fresh_inductor_cache() to clear cached state before mocking the toplevel cache_dir directory. Any lru_caches (or otherwise) can use the @clear_on_fresh_inductor_cache decorator to register the cache for clearing. Also change the base inductor TestCase class to use fresh_inductor_cache(). Previously that TestCase was only mocking the subdirectory within the toplevel cache dir designated for the FX graph cache artifacts.
Test Plan:
- New unit test
- All existing inductor tests will exercise fresh_inductor_cache()

Summary: I plan to enable the FX graph cache for more inductor unit tests. This PR does some refactoring to prepare by moving the `TestCase` base class to `torch._inductor.test_case` (which mirrors the existing `torch._dynamo.test_case`). In a subsequent diff, I'll modify tests importing `torch._dynamo.test_case.TestCase` to use `torch._inductor.test_case.TestCase` instead.
