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

# e8c0849a 20-Nov-2025 Satish Balay <balay@mcs.anl.gov>

Merge branch 'barry/2025-10-18/optimize-aij-ops' into 'main'

Refactor handling of diagonal marking in *AIJ and SELL matrices

See merge request petsc/petsc!8797


# 421480d9 19-Oct-2025 Barry Smith <bsmith@mcs.anl.gov>

- Replace MatMissingDiagonal() and MatMarkDiagonals_SeqXXX() with MatGetDiagonalMarkers_SeqXXX()

- Mat_SeqXXX->diag is not automatically created during MatAssemblyEnd() saving memory and time

- Replace MatMissingDiagonal() and MatMarkDiagonals_SeqXXX() with MatGetDiagonalMarkers_SeqXXX()

- Mat_SeqXXX->diag is not automatically created during MatAssemblyEnd() saving memory and time

- Accessing Mat_SeqXXX->diag now requires the use of MatGetDiagonalMarkers_SeqXXX() except when the current values are known to be correct; for example during numerical factorizations and solves

- Mat_SeqXXX->diag is now never shared among matrices; hence the free_diag flag is gone. That was always a risky proposition since any of the owning matrices could chang the values thus making them incorrect for other owners.
