Review usage of adoptNS()

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Chris Dumez]

Review usage of adoptNS():
1. Make sure we call adoptNS() as soon as we allocate the object instead of doing it later on, as this is less error-prone
2. Fix cases where we called adoptNS() but really should have retained instead of adopting

If you use [m_delegate setOwner:this] instead, this can only be two lines.

The issue is that the type of m_delegate is NSObject, not WebAnimationDelegate. Maybe that still works in ObjC?

As I thought, this does not work:
./platform/graphics/ca/cocoa/PlatformCALayerCocoa.mm:510:21: error: 'NSObject' may not respond to 'setOwner:' [-Werror]
