Apparently it is possible to disable Kokkos Profiling, though it is enabled by default and was specifically designed to have low overhead such that people could reliably leave it enabled. Fix Tpetra::Details::Profiling for that nondefault, generally counterindicated case, by doing nothing if KOKKOS_ENABLE_PROFILING is not defined.
