[Sergio Correia (qrwteyrutiyoup)]

A view being in the "active" state generally means that it is not in the
"background", although this definition can vary depending on the platform
under consideration.

This patch adds the following APIs:
- bool WKCoordinatedSceneIsActive(WKCoordinatedScene)
This API accepts a WKCoordinatedScene as parameter and returns a boolean
indicating whether the given scene is active.

- void WKCoordinatedSceneSetActive(WKCoordinatedScene, bool)
This API accepts a WKCoordinatedScene and a boolean as parameter, and it
sets the active state of given scene to the boolean argument.

Additionally, this patch adds enablers to get the WKCoordinatedScene from
a WKView.

This doesn't belong in WKCoordinatedScene, as it needs to send a message to WebPageProxy/WebPage as well (something like viewStateDidChange), so that the focus controller is aware of the page being deactivated. See how it's done in QRawWebView or QQuickWebPage|View.
