commit 76e9205457111b813ecd8bc36d6c12153b21bd14

chromeos: Move TrayBubbleView from views to ash

It's only used in ash code. It also has aura dependencies, which is
unexpected for general-purpose views code (which supports non-aura
Views on Mac).

This makes it easier to find when we audit code in ash for mustash.
