This PR implements a quasi-3D Poisson solver based on the Integrated Green's functions.
It solves the 2D Poisson equation on the (x,y) plane for every slice z.
It is useful for beam-beam simulations.

See PR #4648 for the full 3D solver.

Notes:

  • docs may be too synthetic
  • CuFFT wrapper has been addded but not tested
