Enable GPU Peer Access in GPU Utilities
When using the new GPU communication features, enabling peer access
between pairs of GPUs (where supported) will allow peer-to-peer
communications. In this patch the CUDA code to enable peer access is
introduced into central GPU utilities and called from do_md.
Implements #3087
