Move sensor collection to all sensors

Redfish's thinking on what sensors should be included in the sensor
collection has changed. Roughly two years ago their thinking was
"for sensors that are not covered elsewhere in the model-meaning do
not duplicate Power and Thermal" and that is what OpenBMC implemented.

Today, as described in the new thermalSubsystem and powerSubsystem doc
the sensor collection should contain all sensors that are associated
with that chassis.

Link with: https://redfishforum.com/thread/190/sensorcollection-contain-all-sensors-chassis

All things considered as "sensors" should be included in the Sensor
collection.

To make this transition as easy as possible for clients, create a new
meson option, new-powersubsystem-thermalsubsystem. This "all sensors in
the sensor collection" behavior as well as the new ThermalSubsystem,
PowerSubsystem, Fans, and Power Supplies schemas will be under this
option. This option is defaulted to disabled. At a later time, the
default will move to enabled.

Move Redfish SensorCollection to show all sensors from
/xyz/openbmc_project/sensors with the "all_sensors" association for that
chassis if this option is enabled.

The SensorCollection is found at /redfish/v1/Chassis/<Id>/Sensors.

Tested:
1. Enabled redfish-new-powersubsystem-thermalsubsystem and
   validator passes.

2. Performance testing (average of 5 times):
   a. Redfish validator time:
      without this patch: 71.375s
      with this patch:    71.763s

   b. Number of sensors tested:
      without this patch: 8
      with this patch:    63

   c. Run `https://${bmc}/redfish/v1/Chassis/chassis/Sensors`:
      without this patch: 0.197s
      with this patch:    0.228s
