thresholds: Add PerformanceLoss threshold

Create an xyz.openbmc_project.Sensor.Threshold.PerformanceLoss D-Bus
interface.  This could be placed on a sensor to:

a) Signal some other software to do something to the server that results
in performance loss, such as memory or CPU throttling, to bring down the
sensor value.

b) Trigger an event to the user so they know to expect a performance
loss, and which sensor caused it.

An immediate use of this will be on OpenPower systems to throttle the
CPU/memory and trigger event logs due to a high (virtual) ambient
temperature.
