Dismiss notifications by swiping right

Add a new interface `NotificationManager::Dismiss(id)` to delete a
notification with the specified `id`.

The animate the notification dismiss the `RightAnim` transition to a
black screen is used. After the dismiss the new message is swiped in
from below or above.

If we dismiss the oldest message (when we are at 5/5, or 3/3), then the
new message after a dismiss should appear to come from below.

Otherwise (when we are at 2/3) the new message after a dismiss should
appear to come from above.

Rework the index code to show the index of the currently viewed
notification. Instead of calculating the index relative to the oldest
`id` introduce a new interface `NotificationManager::IndexOf(id)`. This
is done because the `id` of the notifications in the buffer aren't
continuous anymore (as some messages could have been dismissed).

Rework notification ring buffer to have a beginIdx and a size
internally to make the dismissal of notifications easier.
