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:
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.
