+ SVGViewSpec objects should mark relevant SVG elements

+ <rdar://problem/46491325>
+
+ Reviewed by Ryosuke Niwa.
+
+ SVGViewSpec elements reflect the state of an underlying SVGElement. Teach the mark algorithm to
+ recognize the relevant SVGElement as active as long as the SVGViewSpec is active.
+
+ Update SVGElement so that it can vend WeakPtrs. I also noticed that SVGAttributeOwner used a bare
+ pointer to the SVGElement, so switched to a WeakPtr.
+
+ Test: svg/animations/view-dependency-crash.html
+
+ * Sources.txt: Add new files.
+ * WebCore.xcodeproj/project.pbxproj: Ditto.
+ * bindings/js/JSSVGViewSpecCustom.cpp: Added.

+ * svg/SVGElement.h:
+ * svg/SVGPathElement.h:
+ * svg/SVGViewSpec.cpp:
+ (WebCore::SVGViewSpec::SVGViewSpec): Hold a weak pointer (rather than a bare pointer) to the underlying element.
+ * svg/SVGViewSpec.h:
+ * svg/SVGViewSpec.idl:
+ * svg/properties/SVGAttributeOwnerProxy.cpp: Added.
+ (WebCore::SVGAttributeOwnerProxy::SVGAttributeOwnerProxy): Hold a weak pointer (rather than a bare pointer) to

+ (WebCore::SVGAttributeOwnerProxy::element const): Ditto.
+ * svg/properties/SVGAttributeOwnerProxy.h:
+ (WebCore::SVGAttributeOwnerProxy::SVGAttributeOwnerProxy): Move implementation to cpp file.
+ (WebCore::SVGAttributeOwnerProxy::element const): Ditto.
