Redefine the global event cut to not use UT information

Vladimir Gligorov requested to merge gligorov_remove_ut_from_gec into master

This removes the use of UT information from the global event cut. The default cut value is not changed which as a byproduct means that the GEC in Allen will become more of a "sanity" cut removing only the really few very highest occupancy events, which probably goes in the direction we want to go long-term anyway ( @mvesteri @decianm ). This will be a mess of reference updates and I may well have forgotten something but otherwise is ready for review @dovombru @dcampora @raaij

With this MR, the following slowdown is observed due to loosening the GEC:
