feat(video): Reset view on every YouTube video menu

The row that sets a video back to fresh (its state row and resume point both
go) was only on the feed's cards. It is now on Home's shelves, a Playlists
row's menu and the player's related list too, and is named "Reset view" /
"Megtekintés visszaállítása".
