Enable unit test suite for tvOS (#1649)

Summary:
## Changes in this pull request

Following up on https://github.com/instagram/IGListKit/issues/1401! This PR pulls in koenpunt's PR for tvOS test support and updates it against the latest version of IGListKit.

A few changes:

* I disabled the unit tests that require storyboards/NIBs for tvOS since we only have iOS formatted assets. We can follow this up in a future PR if need be.
* Rewrote the Travis build command for GitHub Actions
* Went through and gated any UIKit APIs that aren't available on tvOS.
* A few unit tests were failing since UICollectionView on tvOS does have a few implicit behavioral differences. I gated these for now, but if anyone using IGListKit on tvOS actually encounters these errors, please open an issue so we can track it and adjust our test suite accordingly.

### Checklist

- [x] All tests pass. Demo project builds and runs.
- [x] I added tests, an experiment, or detailed why my change isn't tested.
- [x] I added an entry to the `CHANGELOG.md` for any breaking changes, enhancements, or bug fixes.
- [x] I have reviewed the [contributing guide](https://github.com/Instagram/IGListKit/blob/main/.github/CONTRIBUTING.md)
