fix: [TypeScript] Remove non-existent methods from <ImageBackground/> (#43290)

Summary:
Using the code from `Test Plan` you will see that `ImageBackground` component doesn't have methods that declared on TypeScript side.

I checked the source code and there is also nothing:

https://github.com/facebook/react-native/blob/d9b0f15c844abce5e97edfd401656d84d0c84133/packages/react-native/Libraries/Image/ImageBackground.js#L47-L69

```tsx
// runtime (React Native 0.73)
 {
  "abortPrefetch": undefined,
  "getSize": undefined,
  "prefetch": undefined,
  "queryCache": undefined,
  "resizeMode": undefined
}
```

## Changelog:

[GENERAL] [REMOVED] - Remove non-existent methods from `<ImageBackground/>` component

Pull Request resolved: #43290

Test Plan:
```tsx
      <ImageBackground
        resizeMode={'contain'}
        ref={ref => {
          if (ref) {
            console.log(' --- xdebug', {
              resizeMode: ref.resizeMode,
              queryCache: ref.queryCache,
              getSize: ref.getSize,
              prefetch: ref.prefetch,
              abortPrefetch: ref.abortPrefetch,
            });
          }
        }}
        style={{
          width: '100%',
          height: '100%',
        }}
        source={{
          uri: 'https://upload.wikimedia.org/wikipedia/commons/8/87/Arturo_Nieto-Dorantes.webp',
