Summary:
We are working on making the empty object literal `{}` have the type `{}` - i.e. exact empty object - rather than being unsealed.
Making this change exposes a variety of errors. We can prevent these errors by annotating what we want the type of the empty object to be.
Reduces Xplat error diff to 2.3k

Summary:
With the new architecture, this diagnostic utility will be helpful to ensure stronger validation of various corner cases at runtime, like handling an early JavaScript exception when loading React Native.
If `global.RN$DiagnosticFlags` is set to a string of comma-separated flags, the util functions will be able to perform additional diagnostics. For now, the accepted flags are:
- `early_js_errors`
- `all`
This is still experimental and may change frequently.

Summary:
Changelog:
[General][Fixed] - Improved Flow type inference in Animated `.interpolate()`
Improves the ergonomics of `.interpolate()` by allowing Flow to infer the correct type for `outputRange`. This is achieved by adding a new type parameter `OutputT` to `interpolate()` (and `Animated.Interpolation` and `InterpolationConfigType`), which Flow infers as either `number` or `string` based on usage.
Admittedly, at the call site, this is not that much safer compared to something like `outputRange: $ReadOnlyArray<number | string>`, but it does document the intent of the API a bit better and provide some downstream type safety. For example, we can now express `Animated.Number` (D35869375) more precisely by excluding string-valued interpolation nodes.

Summary:
Changelog: [General][Added] - Add `Animated.Numeric` Flow type
Adds a Flow type to represent the various Animated node types that evaluate to numeric values and can be `interpolate()`d.
I'm including `AnimatedInterpolation` as "numeric" here even though it can technically evaluate either to a number or to a string, depending on its config. Note that calling `interpolate()` on a string-valued `AnimatedInterpolation` is a runtime error.
In a future diff, I'm planning to add a type argument to `AnimatedInterpolation` (and its config type), at which point we can refine `Animated.Numeric` to correctly include only `AnimatedInterpolation<number>`.

Per https://nshipster.com/image-resizing/#performance-benchmarks, the new API runs even faster than the C version, probably due to more smart context reuses/management.

Summary:
Fixes https://github.com/facebook/react-native/issues/33529 (note that I reproduced the bug on iOS too).
The bug comes from the fact that we were using `this._scrollMetrics.offset` to determine if the initial scroll was done. But sometimes it equals 0 even after the initial scroll is done, for example when the content does not fill the list. So I replaced it with `this._hasDoneInitialScroll`.
I believe that `this._hasDoneInitialScroll` was not used in the first place because it was introduced later (3 years ago vs 5 years ago for the original code).
The replacement correctly fixes the broken test case and the example given in the issue.
Then I had to update two test cases (rename the first and remove the second), that shows explicitly the broken behavior:
we have to simulate the initial scroll for the content to be adjusted, so when the content does not fill the view and the scroll cannot be executed, the content is not adjusted.

Summary:
Changelog: [Internal][SVC][JS] Refactor the JS base SVC StaticViewConfig to be easier to understand
This diff is a refactor that doesn't change any logic.
# Context
NativeViewConfigs are generated from RCTViewManager in iOS and ViewManager in Android.
StaticViewConfigs are partially generated from JS, and partially handwritten in JS.
We've noticed in at least 2 instances that engineers who add new props to NativeViewConfigs sometimes don't put props in the correct place for StaticViewConfigs, and thus they accidentally break the landblocking jest e2e test that validates the StaticViewConfigs matches the NativeViewConfigs.
The human error is mostly because PlatformBaseViewConfig.js was too nested to be easily understood. This diff refactors PlatformBaseViewConfig.js and adds clarifying comments.

Summary:
This drastically improves `Animated.interpolate` performance when `inputRange` has a considerable amount of elements (~100 in my tests).
For instance in `ActivityIndicator` inside `react-native-paper`, the input has 144 elements https://github.com/callstack/react-native-paper/blob/main/src/components/ActivityIndicator.tsx#L170. `react-native-elements` has 9k stars, so I'm assuming this is widely used.
### Cause
The reason for the performance drop is that if we assume `n` to be the size of the range, calculating `'inputRange must be monotonically non-decreasing ' + arr` essentially calculates `arr.toString()` which has O(n) complexity.
Since it is recalculated in a for loop, we end up with `checkValidInputRange` having a O(n²) complexity. Which means ~10k operations if the array has a size close to 100.
## Changelog
[General] [Fixed] - Fix performance issue on Animated.interpolate with big input range
Pull Request resolved: https://github.com/facebook/react-native/pull/33598
Test Plan:
[Here's a repo](https://github.com/Almouro/AnimatedInterpolationRepro) reproducing the issue.
The branch `fix` includes the fix.
Clicking `Interpolate` runs:
```js
new Animated.Value(0).interpolate({
inputRange: Array(144)
.fill()
.map((_, i) => 1 / (i + 1))
.reverse(),
outputRange: Array(144)
.fill()
.map((_, i) => 1 / (i + 1))
```
Here's a comparison of JS thread perf before the fix and after the fix:
- on a Samsung J3 2017 (lower end)
- using Flipper and https://github.com/bamlab/react-native-performance)
- ` __DEV__` mode deactivated
- clicking the button and waiting 15s
| Before | After |
|----------|:-------------:|
|  | |
The error still throws if `inputRange` is incorrect:

Summary:
Allow modifying iOS image cache limits. Currently the image cache imposes some strict limits:
[NSCache.totalCostLimit](https://developer.apple.com/documentation/foundation/nscache/1407672-totalcostlimit?language=objc) of 20MB.
Single Image Size Limit of 2MB (bitmap size).
This may not be enough for applications that make heavy use of images. With this commit it is possible to fine tune them to the applications need.
This can be set for example in the App Delegate with:
```objc
RCTSetImageCacheLimits(4*1024*1024, 200*1024*1024);
```
This would increase the single image size limit to 4 MB and the total cost limit to 200 MB.
