Summary:
This fixes a bug that causes properties to keep stale values because they were not restored to their default after being removed when their value was controlled by native animated.

To fix this we restore default values in `disconnectFromView` by updating views with null values for all props that we modified previously. However this causes another issue where we lose any props that were set by the normal process because NativeAnimated operations are always executed after UIManager operatations. To fix this I added a way to hook into UIManager view updating process to be able to execute NativeAnimated operations either before or after updating native views.

In the case of disconnecting we want to do it before updating views so that it does: Value changed by native animated -> value restored to default -> (optional) value updated by normal prop.

This PR also depends on #10658.

**Test plan**
Tested that this fixed a particular bug in an app that uses ex-navigation + native animations where a navbar w
