Orthogonal views not respecting trailing contentInset

[notjosh]

There is a regression from 3-4 days ago.

As far as I can tell, top and leading are handled here but there's no corresponding trailing/bottom on the other side.

I tried quickly to track it down, but nothing was obvious to me.

Repro up on branch: https://github.com/notjosh/IBPCollectionViewCompositionalLayout/tree/sample-orthogonal-trailing-contentinset (ref: OrthogonalScrollingWithInsetsViewController)

In the screenshots, the top section is scrolled all the way to the right.

There are three issues I see here, two are related to contentInset:

• iOS 12.4 with section contentInset does not include trailing space at the end of the row
• iOS 12.4 with section contentInset makes each of the cells less wide (this seems related to .fractionalWidth, it's the correct size with .absolute()) - we can track this as a separate issue, if it's not related)
• iOS 12.4 doesn't seem to use the bottom of contentInset on items (this seems related, but we can track it as a separate issue)
