Merge branch 'barry/2020-11-11/cleanup-matsetvaluesdevice' into 'main'

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
