This test no longer passes when built with Xcode 15.0.1, likely due to underlying changes in trait collection behaviors with iOS 17+ SDKs.
The failure was:
```
Failure at components/Collections/tests/unit/CollectionsStylerTests.m:180
Assertion Failure at CollectionsStylerTests.m:180: ((lightModeImage) not equal to (darkModeImage)) failed: ("<_UIResizableImage:0x600002dd49a0 anonymous {44, 44} renderingMode=automatic(original)>") is equal to ("<_UIResizableImage:0x600002dd49a0 anonymous {44, 44} renderingMode=automatic(original)>")
```

Removes the need to copy-paste stanzas from other files anymore as we'll rely on #4478 to generate the correct stanza for us instead.

The Info Bar view wasn't correctly applying the z-index value from the
LayoutAttributes. This resulted in the header appearing behind the
collectionView cells on iOS 11.
Closes#1786
* [Collections] Add StylingDelegate methods to control separator display
Adds methods to MDCCollectionViewStylingDelegate, allowing the delegate to control the display of the separator on cells, header and footer.
Closes#1406
* [Collections] Allow custom UIEdgeInsets
MDCCollectionViewController implements custom logic for computing the
`UIEdgeInsets` depending on the `MDCCollectionViewCellStyle` and the
`MDCCollectionViewCellLayoutType`. Subclasses need to override this
functionality to customize their presentation.
* MDCCollectionViewController will use the public
`-collectionView:layout:section` to compute the width of its
supplementary view instead of the internal implementation directly.
* Update the Collections layout example to have different horizontal
edge insets depending on the view's horizontal size class.
Closes#1507
* Add EarlGrey test to verify the insets exampl
* Removing changes to Collection Cells example
* Running code formatter
* Supplemental files.
* Some code clean-up based on willlarche@'s comments
* Removing old header, small cleanup
* Changing block parameter types to match the desired class
* One last id to remove
* Making Earl Grey test a bit better. Some formatting
* Fixing a bug with the flowLayout delegate
