Moving the widget auto-advance logic to AppWidgetHostView instead of

handling it in launcher

This fixes the bug where launcher ignores auto-advance property changes
during app update or widget remote views update as well as simplifies
widget management

On potential downside of this refactoring is that the auto advance will
keep running even when all-apps or widgets tray is open. We could
eventually use onVisibilityAggregated to handle visibility changes,
but currenly the workspace visibility is not being updated properly
in these cases
