Subject: [PATCH] refactor(core): remove duplicated WrappedValue class (#37940)

Before this refactoring we had the WrappedValue class in
2 separate places:
- packages/core/src/change_detection/change_detection_util.ts
- packages/core/src/util/WrappedValue.ts

This commit removes the duplicate, leaving the class that has
the deprecation notice.
