Kevin Delannoy 9ddc64f4ce Add cell (un)highlight APIs
Summary:
This implements the `collectionView:didHighlightItemAtIndexPath:` and `collectionView:didUnhighlightItemAtIndexPath:` `UICollectionViewDelegate` APIs and forward the calls to the appropriate `IGListSectionController`.
For the most part, it's doing the same thing as the `collectionView:didDeselectItemAtIndexPath:` calls and tests are also based on that feature.

- Implements `collectionView:didHighlightItemAtIndexPath:` and `collectionView:didUnhighlightItemAtIndexPath:` in IGListAdapter
- Catch those selectors in `IGListAdapterProxy`
- Adds `didHighlightItemAtIndex:` and `didUnhighlightItemAtIndex:` methods to IGListSectionController and friends (supports `IGListBindingSectionController` via its delegate and `IGListStackedSectionController`)
- Tests for changes

Issue fixed: I didn't open one, so none I guess.

- [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/master/.github/CONTRIBUTING.md)
Closes https://github.com/Instagram/IGListKit/pull/933
