Interface silver mueller (#2051)

* interface silvermueller with refactored boundary interface

* add interface in silver mueller input files

* define first and second half for EvolveB

* add do_pml parse snce RZ needs do_pml to be st to false

* Silver-Mueller boundary condition in docs

* add firsthalf in ApplyBfieldBoundary within PushPSATD as only first first half is used to apply silvermueller

* CallSilverMueller once for all boundaries

* remove unused do silvermueller flag

* fix typo in input file

* Apply suggestions from code review

* abort message if silver-mueller is not selected on all valid boundaries

* fix typo

* fix eol

* remove ifdef from inside the Assert message

* check silver-mueller selection after reading all boundaries
