[Users] PAPI on stampede/mic

Hello Erik, all,

it seems that PAPI 5.3 has options to compile for the mics. One only
has to pass --with-mic to configure. Are you aware of
incompatibilities of PAPI 5.3 or should it be fine to update the
tarball in ExternalLibraries? (CC'd to users at einsteintoolkit.org)

I can compile PAPI 5.3 on stampede and run the papi.par test in
ExternalLibraries/PAPI and get Cache misses (but no timing, but lots
of event-does-not exist warnings):
