Subject: [PATCH] Disable shadow node reference updates by default (#46961)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/46961

Changelog: [Internal]
Runtime Shadow Node Reference Syncing causes asserts when updating the shadow tree without passing through the JS-thread. This diff disables the feature by default to avoid the asserts encountered on RN Windows.
