Stop running devices on vmstop, so that VM does not interact with

Whitelist system handlers which run even when VM is stopped.
These are specific handlers like monitor, gdbstub, migration.
I'm not really sure about ui: spice and vnc: do they need to run?
Yes, vnc and spice should run. They serve the clients. They also don't
change device state.

PS: Well, in the spice case this isn't 100% true, the handlers can
change qxl device state in some cases. But spice has a start/stop
handler which takes care to flush all outstanding work which could
change device state on vmstop, so it is save to keep the handlers active
when the vm is in stopped state.
