Expose DevSettings.openDebugger method to JS (#44934)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/44934

Resubmission of D57681447 with an updated `ReactAndroid.api`.

 ---

Changelog: [Internal]

Adds a private API that gives JS the ability to trigger the same "open debugger" action as in the Dev Menu. This is in preparation for changes to LogBox.

For simplicity, this method operates on a best-effort basis - i.e. it doesn't report the success or failure (or failure reason) of the launch.
