[package] split tests (#53749)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/53749
Split up tests into cases that cover specific functionality. Goals:
1. Avoid the omnibus test file mess (see: test_jit.py) by imposing early
structure and deliberately avoiding a generic TestPackage test case.
2. Encourage testing of individual APIs and components by example.
3. Hide the fake modules we created for these tests in their own folder.
You can either run the test files individually, or still use
test/test_package.py like before.
Also this isort + black formats all the tests.
