windows/svc: add missing Accept commands

Add the remaining AcceptX commands (AcceptParamChange,
AcceptNetBindChange, AcceptHardwareProfileChange, AcceptPowerEvent, and
AcceptSessionChange) to the windows/svc package. Also add support for
these to updateStatus such that a service can actually accept these
commands.
