Do not activate TrayBubbleView by default
- Activating a TrayBubbleView brings an Android window to onPause state.
- This CL sets can_set_activate to false and makes TrayBubbleView not
activated by default.
- If the TrayBubbleView is not activated, it cannot capture key events
for moving focus or closing the view by keyboard. TrayBubbleView tries
to register accelerators at the global level to capture those key
events.
- Activates the TrayBubbleView by default if keyboard navigation
accessibility feature (e.g. spoken feedback) is enabled.
