Subject: [PATCH] Use ClassFinder inside ViewManagerPropertyUpdater (#44114)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/44114

In OSS, we should use the ClassFinder wrapper as the `Class.byName` calls will never succeed (we don't run the annotation processor in OSS).

Changelog:
[Internal] [Changed] - Use ClassFinder inside ViewManagerPropertyUpdater

Reviewed By: arushikesarwani94
