<pre>WebKit scrollbars flash in non-dominant spaces when entering Mission Control

rdar://problem/18195616
Reviewed by Tim Horton.
This patch makes our logic about when to call ScrollableArea::contentAreaDidHide/
Show match the logic in AppKit. We only want these notifications when the window
has become both visible and active (or lost both, in the case of hide).
Re-name setIsVisibleInternal() to setIsVisibleAndActiveInternal(), and call it
only when both visibility and active-state have changed.
* page/FocusController.cpp:
(WebCore::FocusController::setViewState):
(WebCore::FocusController::setIsVisibleAndActiveInternal):
(WebCore::FocusController::setIsVisibleInternal): Deleted.
* page/FocusController.h:
FocusController::setViewState() is the only place that needs to call
ScrollableArea::contentAreaDidHide/Show, so remove these callers.
* page/FrameView.cpp:
(WebCore::FrameView::didMoveOnscreen): Deleted.
(WebCore::FrameView::willMoveOffscreen): Deleted.
* page/FrameView.h:
