thresholds: Add threshold alarm signals

Define signals on every sensor threshold interface that can be sent when
a threshold alarm value changes.  The signal contains the sensor value
that caused the alarm change.

<Threshold Name>HighAlarmAsserted:
 * Sent when the Warning/Critical/etc AlarmHigh property is asserted

<Threshold Name>HighAlarmDeasserted:
 * Sent when the Warning/Critical/etc AlarmHigh property is deasserted

<Threshold Name>LowAlarmAsserted:
 * Sent when the Warning/Critical/etc AlarmLow property is asserted

<Threshold Name>LowAlarmDeasserted:
 * Sent when the Warning/Critical/etc AlarmLow property is deasserted

The threshold name, like 'Critical', is in the property name so that the
generated C++ names are unique and a class can implement multiple
thresholds at once.
