Minor cleanup of Fortran binding stuff to simplify future maintainance

Minor cleanup of Fortran binding stuff to simplify future maintainance

There 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

Fortran 90: fully embrace After 34 years!

- deprecate use of 'F90' in Fortran function names
- use Fortran pointers when appropriate
- the new Fortran API is not backward compatible with previous versions!
- also clean up inconsistent PETSc code detected by new Fortran generation tools
- drop use of bfort
- automatically generate all the Fortran PETSc objects, enums etc from the include files
- generate most of the Fortran interface definitions and functions from the source code
- simplify the number and organization of Fortran modules
