This makes it so entities that are passengers of other entities no longer count in the parents timings, as well as tracks them as a separate timers per their tick status. This lets you see how much time is spent in activated entities vs inactive (as inactive still has to do work) Passengers is also tracked separately so you can identify "Villagers in Minecarts" vs roaming villagers, as the lack of ability to move can impact their performance characteristics. This will likely break any plugin that was naughty and directly messed with our internal timings as this moves the timings to the EntityTypes object, speeding up creation of Entities to no longer store a timing handler object per entity. This will also change the output of the entities in timings to use internal ID's instead of class names. If a plugin is broken by this, shame them for doing bad things. Paper will not fix it, they will have to fix it.
