The following is a list of prefs for which we call `Add*VarCache()` when the pref even exist yet. (This is just during browser startup; there may be additional cases when running different workloads.) In that case, the VarCache variable takes the default value, and if the pref is created later on then the VarCache variable will be updated. It's a pretty gross pattern, and the kind of thing I want to outlaw, so these ones should be considered higher priority cases to convert to static prefs. I will convert `privacy.firstparty.isolate.block_post_message` myself because it's causing problems for me in bug 1569526.
