fvModels: Remove 'Source' from names

The fact that these names create sources in their associated transport
equations is clear in context, so the name does not need to contain
'Source'.

Having 'Source' in the name is a historic convention that dates back to
when fvModels and fvConstraints were combined in a single fvOptions
interface. In this interface, disambiguation between sources and
constraints was necessary.

The full set of name changes is as follows:

                   accelerationSource -> acceleration
                  actuationDiskSource -> actuationDisk
     effectivenessHeatExchangerSource -> effectivenessHeatExchanger
               explicitPorositySource -> porosityForce
            radialActuationDiskSource -> radialActuationDisk
                      rotorDiskSource -> rotorDisk
             sixDoFAccelerationSource -> sixDoFAcceleration
         solidEquilibriumEnergySource -> solidThermalEquilibrium
          solidificationMeltingSource -> solidificationMelting
                 volumeFractionSource -> volumeBlockage
    interRegionExplicitPorositySource -> interRegionPorosityForce
       VoFSolidificationMeltingSource -> VoFSolidificationMelting

The old names are still available for backwards compatibility.
