Fix Popup window flow to work with synchronous compositor gfx mode
This switches around the object lifetimes, so WebContents and AwContents
(native) have identical lifetimes, but now the native AwContents may
exist before its java counterpart, and in the popup flow the java
object may switch from its default peer instance to acquire the pop-up
AwContents/WebContents instead.
Additionally, makes some simplifications to the way AwSettings is created
and also fixes a potential leak (the native instance was never deleted if
destroy() was not called).
