Minor cleanup of Fortran binding stuff to simplify future maintainanceThere is no distinction between F90 and non-F90 code so combine ftn-custom and f90-custom directories and fortranimpl.h and f90
Minor cleanup of Fortran binding stuff to simplify future maintainanceThere is no distinction between F90 and non-F90 code so combine ftn-custom and f90-custom directories and fortranimpl.h and f90impl.h files. Also move uses of f90 to ftn when simple

This requires some changes to user FORTRAN codePass PETSC_NULL_XXX_ARRAY when passing a NULL as an argument that is expecting an arrayPass PETSC_NULL_ENUM when argument returns an enum instead of PETSC_NULL_INTEGERPass arrays (and not scalar values) when the argument is expecting an array; this means replace, for example, the argument v with [v]Use PetscObjectIsNull(obj) to check if the object is NULL, instead of obj == PETSC_NULL_XXXThe compiler will now automatically prevent you from using the wrong argument type for the first three bullets aboveThis will also require an update sowing with the new sowing branch this MR is using.
Remove now redundant increase in mat nonzero state
