MatSetValuesDevice: Cleanup and simplify code, including example

See merge request petsc/petsc!3411

MatSetValuesDevice: Cleanup and simplify code, including example

User reported crash of example code. Kernel was passed an ierr that lived in CPU memory

MatSetValuesDevice: do not include private h

MatSetValuesDevice: Cleanup and simplify code, including example

User reported crash of example code. Kernel was passed an ierr that lived in CPU memory

MatSetValuesDevice: do not include private headers from public headers

Feature: MatSetValuesDevice determines automatically from the context (where it is included from) if it is being used from C, CUDA, or Kokkos, PETSC_DEVICE_FUNC_DEC no longer needs to be set before including petscaijdevice.h

Feature: MatSetValuesDevice() now ignores all values outside the global column range.

PetscSplitCSRDataStructure is now a pointer, not a struct, like most PETSc objects, please leave it that way.

Fix all uses of CTABLE that were related to the original MatSetValuesDevice()

Have atomicAdd use Kokkos atomic-add with CPU build when building with Kokkos.

Cuda should now work with --download-openmpi, this is done by updating updateCompilers() to rerun portions of packages/cuda.py after the compilers are reset to use MPI wrappers. This is needed because the resetting of the compilers removes all the compiler flags and packages/cuda.py sets certain values into these flags that was previously lost.

Add MPICXX_INCLUDES, MPICXX_LIBS to fix compile targets for Kokkos examples

'make check' now runs properly for Kokkos test of src/snes/ex3k, fixed bug in the makefile wrt MPI_IS_MPIUNI check

Testing makefile rules: add ex*cu binaries to clean rule

Change MatFactorGetUseOrdering() to MatFactorGetCanUseOrdering()

See merge request petsc/petsc!3739

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 factorizatio

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
