ui/gfx: Add ToString() function to Point class.

So we don't need to override operator<< for Point class.

I believe we define this operator for a handful of classes. Is there a reason
you want to remove it?

Not one specific, I was looking into Insets class and noticed that it doesn't
have this operator, then I came to http://codereview.chromium.org/497004 which
you request to not override operator<<, so then I though we could fix the others
class as well and add ToString() to Point/Size/Rect. So then I started fixing
Point and was planning to do the same thing later for Size and Rect.
