fix crash in adjustForMaintainVisibleContentPosition (#53208)

Summary:
Pull Request resolved: #53208

changelog: [internal]

When Fabric View Culling is enabled together with immediate state update, it may lead to a crash inside of `[RCTScrollViewComponentView _adjustForMaintainVisibleContentPosition]`.
When doing immediate state update, we can avoid calling `[RCTScrollViewComponentView _adjustForMaintainVisibleContentPosition]` altogether to avoid the crash.
