Make ReactPackageLogger internal (#49236)

Summary:
As part of the initiative to reduce the public API surface, this class can be internalized. I've checked there are [no relevant OSS usages](https://github.com/search?type=code&q=NOT+is%3Afork+NOT+org%3Afacebook+NOT+repo%3Areact-native-tvos%2Freact-native-tvos+NOT+repo%3Anuagoz%2Freact-native+NOT+repo%3A2lambda123%2Freact-native+NOT+repo%3Abeanchips%2Ffacebookreactnative+NOT+repo%3AfabOnReact%2Freact-native-notes+NOT+user%3Ahuntie+com.facebook.react.ReactPackageLogger).
