Merge branch 'jolivet/fix-unnecessary-reduce' into 'main'

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.
