KOKKOS: empty bogus kokkoscore property
In !2679 (merged) we emptied INTERFACE_COMPILE_DEFINITIONS
since it lead to errors to our users while configuring using vtk+vtk-m+kokkos+hip. @ayenpure reported the same error with vtk+vtk-m+kokkos.
Here I move the statement to empty INTERFACE_COMPILE_DEFINITIONS
for every kokkos device, not only HIP.
