feat(Android): add support for invert colors check on android accessibility (#47341)

Summary:
This PR provides a fix for the long existing issue of missing check for invert color in accessibility options on Android.
Reference Issue : https://github.com/facebook/react-native/issues/30870

## Changelog:
- Added native module code to check for invert color settings value
- Updated js module to return a proper promise instead of default false for isInvertColorsEnabled()

[ANDROID] [FIXED] - Missing isInvertColorsEnabled implementation for Android

Pull Request resolved: https://github.com/facebook/react-native/pull/47341

Test Plan: Tested on OnePlus 12 with Android 14 and Pixel 6 with Android 15. The try catch exists because in some cases if the switch hasn't been toggled before the android system raises the missing settings exception.
