wmc: add Access Technology/Service definitions and Global Mode stuff

Comparing dumps from UML190 in different modes, UML290, and PC5740
revealed what the 'service' bit was, which matches up nicely with
the SERVICE_* strings in the Windows connection manager DLLs if
you interpret them in reverse numerical order.

For the global mode stuff, looking at USB wire captures shows that
C8 03 and C8 04 get used right before the NETWORK_INFO (C8 0B)
shows access technology changes, which means they are probably the
commands that switch global mode around.
