Content should not have knowledge of NaCl. Moving per process NaCl debug
stub port information to NaClBrowser.

More explicitly distiquish between the case where the debug port is not yet
known versus when it is unused.

Switch debug port to being a per-process value (as it is).

This relands r270907 with a fix to make it work with disable_nacl=1
and therefore ASAN.
