Add automatic generated fortran support for setting and returning contexts

Major cleanup of the code for setting and returning application (previously called user) contexts
- PetscCtx ctx is now the standard for passing in contexts
- PetscCtxRt ctx is the standard for passing out contexts, including context destroy routines based on PetscCtxDestroyFn

Both of these are typedef to void*

Also removed most use of user and userctx for context arguments now consistently named ctx

Improved documentation on PetscCtx and PetscCtxRt and on how to use contexts (including getting them) from Fortran

Changes to allow building gpu matrices on the device.

Changed MatCreateMPIAIJWithSeqAIJ() so global sizes must be given to prevent reduction.

Changed MatCreateMPIAIJWithSeqAIJ() so B can be passed in with local indices, hence no compactification occurs.

Added MatCreateSeqAIJKokkosWithKokkosViews() which creates a Mat with no preallocation on the host.

Added test that checks building kokkos matrices without any host preallocation

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
