(#8272) Allow disabled Windows services to be started

Because Windows allows a service to be both running and disabled, we now
support that capability. If a service is explicitly requested to be running and
disabled, we will set it to manual start if necessary, start it, and then
disable it. If the service is requested to be running and enabled, we will now
enable it before attempting to start it (previously, this would simply try to
start it and fail).

The exception to this rule is a service which is disabled, and for which we are
not managing the enable property. In that case, we assume that some other
authority has disabled the service, and respect that, failing to start. Thus,
if the user actually wants a service to be running and disabled, they must
explicitly declare that intent.
