Support headers [crossOrigin and referralPolicy] in Image without src and srcSet and only remote source.uri (#50799)

Summary:
Resolves #50778

### Problem Description

Implement the crossOrigin property for Image in RNW Fabric when only source.uri is passed and not src/ srcSet.

For reference, check the public API documentation: https://reactnative.dev/docs/image#crossorigin

Implement the referrerPolicy property for Image in RNW Fabric when only source.uri is passed and not src/ srcSet.

For reference, check the public API documentation: https://reactnative.dev/docs/image#referrerpolicy

Also refer docs for source, src, srcSet
https://reactnative.dev/docs/image#source
https://reactnative.dev/docs/image#src
https://reactnative.dev/docs/image#srcset

It's not mentioned in the doc that when src / srcSet is missing then crossOrigin / referralPolicy would be ignored when source uri is a remote URL that is passed.

Currently these were ignored if src / srcSet was not passed and not added to sources headers.

This change adds headers support even without passing src / srcSet and only sources uri that consists of remote URL.

crossOrigin and referrerPolicy are passed as source.headers here:

### Steps to reproduce

```
 <Image
              defaultSource={{uri: this.state.defaultImageUri}}
              source={{uri: this.state.imageUri}}
              crossOrigin="use-credentials"
              referrerPolicy="no-referrer"
            />
```

Pass this in React Native and check source headers
