Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51211
Changelog: [internal]
This modifies the setup for Fantom so:
1. We don't inject "InitializeCore" by default.
2. We define a default environment setup module for Fantom with good defaults (LogBox, etc. disabled).
We also migrate all existing tests to use the new module.
The goal of this is to prevent LogBox from being used in tests so we can properly fix error propagation in the work loop (so they're not intercepted by it).

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51174
Allows the start and end of the scrollview to be faded to different values independently by passing an object containing a "start" and "end" value to the fadingEdgeLength prop.
To support non-uniform edge lengths we use the [FadingEdgeStrength](https://developer.android.com/reference/android/view/View#getTopFadingEdgeStrength()) api to set different values for the start/end of the scrollview. The FadingEdgeStrength value is multiplied by the FadingEdgeLength value [internally by Android when drawing the view.](https://cs.android.com/android/platform/superproject/+/android15-qpr1-release:frameworks/base/core/java/android/view/View.java;l=25007)
Because the value of FadingEdgeStrength is required to be between 0 and 1, we set setFadingEdgeLength to the max value and set the smaller side as a percentage of that value.

# Why so many tests?
Differentiator has two modes: regular and reparenting. The reparenting one is almost a completely separate Differentiator, effectively doubling the complexity. It handles quite a few different special cases and is not covered by any reasonable tests, so here I am adding the tests to make sure every branch of the reparenting Differentiator is traversed.

This fixes a potential bug where we coalesce unique events with non-unique ones of the same type and target.
Not marked as a bug fix in the changelog because this wouldn't happen in practice, as we always dispatch events of a given type the same way (all unique or all non-unique).

changelog: [internal]
Group tests related to reparenting in "describe" block. Differentiator is two algorithms hidden behind a single interface: regular and reparenting. The tests are structured this way as well where regular tests focus on common scenarios and reparenting section focuses on reparenting and special cases around that. The reparenting implementation is considerably more complex as it handles edge cases that don't happen often.

});
Fantom.runWorkLoop();
```
Now, you can just do:
