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

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

More improvements to Fortran stubs and interfaces

This requires some changes to user FORTRAN code

Pass PETSC_NULL_XXX_ARRAY when passing a NULL as an argument that is expecting an array
Pass PETSC_NULL_ENUM when argument returns an enum instead of PETSC_NULL_INTEGER
Pass 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_XXX

The compiler will now automatically prevent you from using the wrong argument type for the first three bullets above
This will also require an update sowing with the new sowing branch this MR is using.

Plex: More work adding in CEED backend
- Add DMPlexGetUseCeed() and DMPlexSetUseCeed()
- Need to propagate useCeed flag
- When using CEED, make tensor order the default, but shut it off for matrix insertion since this is still done by Plex kernels
- DMPlexMatSetClosureGeneral() now takes flag for closure permutation
- Add DMPlexMatSetClosure_Internal() which takes flag for closure permutation
- Add DMPlexVecGetClosure_Internal() with flag to turn off closure permutation - Turn off closure permutation in L2 diff calculation
- Add DMUseTensorOrder()
- Add DMPlexSNESComputeResidualCEED() - Cleanup SNES ex13 - Do not give CEED negative offsets
