Convert SIMDRecoStats to use new Gaudi counters

Converts the monitoring algorithm used by the RICH to use the new Gaudi counters from @sponce instead of my own home grown tallies. Both reduces the amount of boilplate code, but also I hope will help to remove opt versus dbg differences as with this the RICH numbers are compared properly as counters (with a reasonable precision) instead of indirectly via the log file diff.

@cattanem WIP as, obviously, will affect the tests in the nightlies, so please test at your convenience.

Example of the output expected is
