Replaces old and simple usages of std::atomic<bool> with Common::Flag (which was introduced after the initial usage), so it's clear that the variable is a flag and because Common::Flag is well tested. This also replaces the ready logic in WiimoteReal with Common::Event since it was basically just unnecessarily reimplementing Common::Event.
