Clean up the way top level navigations are handled in ChromeFrame and reported back

to the host browser. We no longer have a counter which tracks the last page id.

Top level navigations are reported back if the current frame does not have an opener
or if the origins don't match. The other conditions remain the same i.e reloads/back forwards
and posts don't make it to the host browser and are treated as internal navigations.

This fixes bug http://code.google.com/p/chromium/issues/detail?id=52931

Disabled the navigate out chrome frame test as this needs to be fixed to propertly detect
navigations coming out of chrome frame.
