Scroll to make the video element visible when exiting fullscreen.

https://bugs.webkit.org/show_bug.cgi?id=141439

Patch by Jeremy Jones <jeremyj@apple.com> on 2015-03-06
Reviewed by Simon Fraser.

Source/WebCore:

This patch will scroll the element so it is visible when exiting fullscreen,
but only if the element is completely scrolled off screen.
Also update the element screen rect so exit animation goes to the correct location.

* dom/Element.cpp:
(WebCore::Element::scrollIntoViewIfNotVisible): Added.
* dom/Element.h: Add declaration for scrollIntoViewIfNotVisible.

This patch will restore interface state when exiting fullscreen.
Adds preparedToReturnToInline to continue exiting once the interface is updated.
