Here is output from the stream.cuda in the Kokkos-core benchmarks directory run on Perlmutter on 1 GPU. The number of bytes in the HighWater at the last point in time shown in the first table is equal to the data transferred between host and device.

This PR adds memory transferred between Kokkos Mem Spaces to the Kokkos Tools memory-usage tool library. This is done based on a request in Kokkos Tools Github Issue #50.
This PR adds functionality to the tool so that the size of data transferred in the deep_copy in a Kokkos application program is accumulated during the execution of a Kokkos program. The deep_copy accumulation is done per Kokkos Memory Space dst->src pair (e.g., OpenMP on host CUDA on device). Note that the "dst" and "src" Kokkos memory space being the same means that there was a deep_copy in the same memory space.
When Kokkos is finalized in a Kokkos application program, the finalize callback prints out the deep_copy accumulations per memory space to the file.
