[iOS WK2] Make view debugging easier
https://bugs.webkit.org/show_bug.cgi?id=132892

Reviewed by Tim Horton.

Enhance -[WKCompositingView description] to show WebKit-related information
which is useful when dumping a window's UIView hierarchy.

Also have WKTransformView and WKRemoteView inherit from WKCompositingView,
and thereby get the hitTest:withEvent: override for free, as well as better dumping.

(-[WKTransformView hitTest:withEvent:]): Deleted.
(-[WKRemoteView hitTest:withEvent:]): Deleted.

Safari requires the viewport meta tag width for legacy stuff on WebApps. Just send it

Subpixel layout: Change Element.offset* client* scroll* return type to double.
https://bugs.webkit.org/show_bug.cgi?id=132895

Reviewed by Simon Fraser.

Source/WebCore:
This patch changes Element.offset*, Element.client* and Element.scroll* APIs return
type from long to double to match the latest CSSOM View Module spec[1].
Element.offset* and Element.client* do return subpixel values from now on.
Element.scroll* still return integral values as the scrolling code hasn't adopted to subpixel rendering yet.

subpixelCSSOMElementMetricsEnabled setting is added to be able to turn this feature on/off
from WK2 preferences. It toggles the return value from subpixel to floored integral.
It does not change layout/rendering behavior.

It mostly means adding Math.round() before comparing values in order to match pixelSnappedIntRect()
