Input parameter for AMReX MLMG verbosity (#2041)

* Added warpx_solver_verbosity input parameter

- This input paramter is for the electrostatic solver to pass into
  MLMG::setVerbose(int)
- Originally this value was hardcoded to 2

* readded accidently deleted line

* Handle the default solver_verbosity value on the C++ side

* Verbosity parameter now works the same as warpx.self_fields_max_iters

- The input parameter for mlmg verbosity is now warpx.self_fields_verbosity
- It still has a default value of 2.

* fixed missing comma

* added missing parameter to function call

* Added documentation entry for warpx.self_fields_verbosity

* corrected documentation

* fixed formatting mistsake
