Sensors: Add SpeedRPM property

Changes here are to add support for Redfish for Thermal Equipment[1].

Add the SpeedRPM property for a Rotational fan sensor. This property is
part of the Redfish Sensor schema since version 1_2_0.[2]

This change is so we will always have a property with the RPM. This
allows a client (e.g. webui-vue) to always look for the SpeedRPM
property.

Note: Redfish defines the Reading property for a fan to be a
percentage value. Currently for this type of fan sensor the Reading
value is being set to the RPM value. To preserve backwards
compatibility the SpeedRPM property is added without altering the
Reading value. However this may change in the future to match the
expected Redfish implementation. Clients are advised to use the new
SpeedRPM value to assure continuing correct function.

Implementation Note: The objectPropertiesToJson() has existing  else
if(sensorType ==) statements. However because the first if()
statement is looking at the chassisSubNode these are never visited for
sensors when using the
/redfish/v1/Chassis/<chassisId>/Sensors/<sensorName> URI.
Those existing sensorType comparisons are used for the
redfish-allow-deprecated-power-thermal Redfish interfaces.
