CMake: FindKOKKOS: Work around configuration failure

Configuration did fail in the following situation
 - Kokkos installed via Trilinos (MPI enabled)
 - deal.II configured without MPI

In this situation FindTRILINOS.cmake bails out because of an MPI
configuration mismatch, so the manual search for Kokkos in
FindKOKKOS.cmake is triggered. The latter one fails because Kokkos
installed via Trilinos did export a valid project configuration only
containing the Kokkos::kokkos target and not the Kokkos::kokkoscore
target.

Work around this issue by only configuring if Kokkos::kokkoscore has
indeed been imported.

To keep reading input consistently this also requires that we slightly modify
the cell inversion algorithm. This is backwards-compatible since the option to
use the new style ordering was added in 7f9c1023b61.

Get rid of create_triangulation_compatibility in the UNV reader.

This case is interesting since the current code only works by coincidence. Our
test files have vertices numbered like

    2 ---- 3
    |      |
    |      |
    1 ---- 0

which we read in in the old-style (UCD) numbering, which is like mirroring
across the y-axis. This causes all the cells to have a negative measure (but they
aren't pinched). GridReordering then fixes this by swapping vertices 1 and 3 of
every single cell - i.e., adding another -1 factor to the measure, which now
causes all cells to have positive measure. Something similar happens in 3D.

As far as I can tell there is no widely accepted node numbering for UNV like
there is for everything else so I am going by what Salome generates. Since we
now use their numbering directly (instead of something that worked by
coincidence) the output files are slightly different but all cells do end up
looking correct (nothing is twisted when we visualize with VTK).
