feat(image): enabling basic cache control for android (facebook#47182)
Browse files Browse the repository at this point in the history
Summary:
Fixes facebook#12606

Previously, `Image` cache control options were not functional on Android, even though they were being passed to the native component via the `source` prop. This PR addresses that by implementing logic to manage cache behaviour on Android.

When the `reload` option is explicitly set, the image is now evicted from both memory and disk caches before a new request is made. This ensures the image is always fetched from the source, aligning the caching behaviour between Android and iOS for the `default` and `reload` options.

## Changelog:

[ANDROID][ADDED] - Enabling basic `Image` cache control for Android

Pull Request resolved: facebook#47182

Test Plan:
Added a new example to the `rn-tester`, where we can notice that the image on the right is reloaded if rendered or re-rendered as the cache policy is set to `reload`. The image on the left has the cache policy set to `default` and won't be re-rendered as the image is already in the cache.  See the video below:

https://github.com/user-attachments/assets/88bc1d2d-0239-4deb-bcde-fe0ce521ff4d

Also tested on both old and new architecture.
