In Ivy, we support a new manual mode that allows for stricter control over change detection in OnPush components. Specifically, in this mode, events do not automatically mark OnPush views as dirty. Only changed inputs and manual calls to `markDirty()` actually mark a view dirty. However, this mode cannot be the default for OnPush components if we want to be backwards compatible with View Engine. This commit re-adds the legacy logic for OnPush components where events always mark views dirty and makes it the default behavior. Note: It is still TODO to add a public API for manual change detection. PR Close #28474
