Deprecate ImageBackground (#57412)

Summary:
Deprecates `ImageBackground` as part of the effort to keep core lean. It is a thin wrapper around a `View` and an `Image`, and can easily be replaced by composing a `View` with an absolutely positioned `Image` and layering children on top:

```tsx
import type { ReactNode, Ref } from "react";
import {
  Image,
  StyleSheet,
  View,
  type ImageProps,
  type ViewProps,
} from "react-native";

type ImageBackgroundProps = Omit<ImageProps, "style"> & {
  children?: ReactNode;
  ref?: Ref<View>;
  style?: ViewProps["style"];
};

export const ImageBackground = ({
  children,
  importantForAccessibility,
  ref,
  style,
  ...props
}: ImageBackgroundProps) => {
  const { height, width } = StyleSheet.flatten(style);

  return (
    <View
      ref={ref}
      accessibilityIgnoresInvertColors={true}
      importantForAccessibility={importantForAccessibility}
      style={style}
    >
      <Image
        {...props}
        importantForAccessibility={importantForAccessibility}
        style={[StyleSheet.absoluteFill, { height, width }]}
      />
      {children}
    </View>
  );
};
```

## Changelog:

[GENERAL] [DEPRECATED] - Deprecate `ImageBackground`, use a `View` with an absolutely positioned `Image` instead

Pull Request resolved: #57412

Test Plan:
- `deprecated` shows a strikethrough on `ImageBackground` in editors.
- Importing/rendering `ImageBackground` logs the deprecation warning once.
