feat(servers): time the main loops' phases and the known heavy spots

Browse Source 
Frames and phase scopes in the world, auth, chat and UGC loops (packets per type, entities, physics, ghosting, replica, spawners, log flush, saves, web requests by route). Scopes at LoadPlayer, CreateEntity, each component's construction, InventoryComponent::LoadXml, script timers and a world's zone load; game database queries in the query helpers; CDClient statements timed through sqlite3_trace_v2 as CDClient <table> (CppSQLite3DB gets a handle accessor). Task 96.
