Subject: [PATCH] Introduce launchable versions of common view types.

These can be used instead of the base types by views that want to use
container launch animations, to avoid duplicated boilerplate due to
implementing LaunchableView.

Bug: 250588519
Test: manual
Change-Id: I355b1a8de933c61313372fc7e00791cd0faef629
