Ability to crop images attached to posts (#2531)

* First attachment crop attempt: Can crop in place, but does not delete/replace on server so has no effect

* Attachment crop feature works

* ktlint fixes on attachment crop patch

* Upgrade Android-Image-Cropper to 4.2.1

* An error message should be displayed if attachment cropping fails and it is not because the user intentionally cancelled.

* Remove 2 of the 3 "state passing" variables by using MediaUtils

* Cropper should use content uri (MIME type bearing) and setOutputCompressFormat so that PNGs reach the server safely.

* Change to crop requested by Conny: Store inflight cropImageItemOld in view model

* Change to crop requested by Conny: Sort cropImage with the other contracts

* ktlint fixes on attachment crop patch (again)
