The native port callback is now passed the message as a decodes
Dart_CMessage structure. The Dart_CMessage structure is allocated
in a zone and the callback receiving it should expect the
lifetime to be controlled by the caller.
Added support for zones which do not require a current
isolate. Changed the GrowableArray to support allocating in
aprovided zone instead of the zone for the current isolate.

Dart_NewNativePort creates a port associated with a C handler
function. When messages come in on this port, they are forwarded to
the C function for processing.
To support this, refactored PortMap so that it operates on a new
MessageHandler type instead of directly on Isolates.
For now, native ports have a dedicated single thread. Eventually we
will back native ports (and possibly Isolates as well) by a shared
thread pool.
