Fix CPUParticles emission updating using physics interpolation

Browse Source 
When switching emission on and off, processing was always being switched on and off using internal_process, which was incorrect for using physics interpolation (where physics_process is the relevant one).

This PR correctly updates the process mode according to whether physics interpolation is being used.
