content: Move collected cookies constrained window to TabContentsWrapper.

To split the ConstrainedWindow feature off of TabContents entirely (moving it
to a helper object on TabContentsWrapper), I'll need to first make each
constrained window TabContentsWrapper aware first. I started just hacking

So my current plan to move the constrained window stuff from TabContents to
TabContentsWrapper is to start by migrating all the codepaths that generate
constrained windows to TabContentsWrapper so the patch that moves ownership from
TabContents to TabContentsWrapper just deletes a lot of "->tab_contents()" that
I'm adding in the meantime.
