MVVM - Introduce some helpers for snapshot management (#30398) ...

* Introduce snapshot class to track snapshot updates

This avoids the hassle of having to manually call emit.

* Better viewmodel ergonomics

- Rename `SubscriptionViewModel` to `BaseViewModel`. I feel this is
  appropriate since that class does more than just manage subscriptions.
- `getSnapshot` is no longer an abstract method. It's simply a method
  that returns the current snapshot state. This ensures that getSnapshot
result is cached by default which is required by `useSyncExternalStore`.
- `props` are a property of the base vm class so that actual VMs don't
  have to keep creating this property.

* Update `TextualEventViewModel`

* Fix test

* Rename `TextualEvent` to `TextualEventView`

* Fix snapshot object not being merged

* Rename directory to `EventTileView`

* Fix broken snapshot

* Add test for snapshot class
