Summary:
This diff adds more enforcement for consistency of `ShadowNodeMutation`s, including:
* `Props` object for newly created or updated view must not be nullptr;
* `oldShadowView` must describe the previous state of the view for `Update` instruction;
* `ignoreDuplicateCreates` option was removed.
I suspect some of the crashes we see in Fabric are caused by a violation of one of these constraints. If one of these fails in debug builds, we will get an early signal.

Summary:
Index adjustment is tricky. Seems more reliable to adjust each immediate mutation, and then immediately adjust delayed mutations based on it, rinse and repeat.
Previously it was possible to construct examples where the UI would get into a weird state because index adjustment caused items to be inserted in the wrong location.

Summary:
1. When testing major changes to the differ, it can be useful to have more verbose logging.
2. On Android, since asserts don't fire yet, I log which asserts are failing.
Should have no impact on any builds unless you manually set the macro here, and it will have no impact on production builds regardless.
