Delete custom _load_config_used

_load_config_used is a magic global that is used to configure how a
process on Window starts up. We modified it in 2015 to change how the
heap works, but it is not clear whether this was beneficial, and it
means that we are now missing some changes to that structure. The
cost/benefit analysis says that our custom structure isn't worth it.
