Fix kokkos test with mpi_gpu_aware

We know at compile time whether an mpi implementation is gpu
aware so know not to test gpu_aware mpi when it is not present.

Merge branch 'rmills/feature-matgetcolumnreductions' into 'main'

Add MatGetColumnReductions()

See merge request petsc/petsc!4272

Add MatGetColumnSums() and MatGetColumnMeans() (and real and imaginary part variants)

MatGetColumnReductions() now takes a PetscInt so ReductionType or NormType members can be passed.
