Introduce PCFactorSetDefaultOrdering_Factor() to allow each factorization package
to indicate its preferered ordering, which may be external (its own) or one of PETSc.

Introduce PCFactorSetDefaultOrdering_Factor() to allow each factorization package
to indicate its preferered ordering, which may be external (its own) or one of PETSc.

This also affects factorization like dense PETsc where the ordering passed in by PETSc is ignored and not needed.

Also fixed options for MUMPS and SuiteSparse where users needed to pass a particular options database option
to the package (MUMP or KLU) indicating they should use the PETSc provided ordering. Now if the PETSc provided ordering is provided
these packages automatically use them without need a special option. This simplifies ordering usage for external packages
