Enable physics interpolation in all demos that use physics

This also improves visuals in the Voxel and Dynamic Split Screen demos,
and fixes splitscreen mode in the Platformer 2D demo.

Most demos (other than physics tests) have also had their physics FPS
increased to 120. This is done consistency with 4.x, but also for the
benefits it still provides when interpolation are enabled
(lower input lag, more stable simulation).
