Pull Request resolved: https://github.com/facebook/react-native/pull/30988
We have a bunch of flags scattered throughout the codebase with poor hygiene and commenting. Consolidate.

Summary:
iOS and Android platform code already explicitly check this invariant: nodes cannot have parents when they're inserted into the View hierarchy.
Check this in the core so we get these checks in unit tests, and earlier in the core before platform code runs.

Summary:
On iOS, log lines are not entirely flushed when an assert is hit right after (or during) this mutate function. Make sure to flush log lines regularly during this function so that debugging is easier.

The assert is still firing, let's disable it until we can investigate why layout animations creates two delete mount instructions.

Summary:
The current implementation of LayoutAnimations assumed that the "previous/old" ShadowView passed into the diff mutation didn't matter except for purposes of diffing.
As it turns out, iOS components could possibly use the "old" version of props, state, etc - so we should try to keep track of the current value in the tree as much as possible.
This diff accomplishes that by keeping track of the "previous" view, which the AnimationDriver will update over time. This also allows us to simplify logic around conflicting animations.
I'm also adding a few additional asserts to assist in debugging.
This doesn't totally eliminate all asserts hit on iOS, yet, but it does reduce the number of times the asserts are hit in StubViewTree.

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.
