Kyle Spier-Swenson 565319095f Adds MC initialization stages. Earlier stages can fire while later ones init. Fixes tgui chat reconnection banner showing during init. (#66473)
* Adds MC initialization stages. Earlier stages can fire while later ones init.
Removes TICK_LIMIT_MC_INIT config for barely doing anything to speed up init and being inconvenient to work with if fires and inits can happen at the same time.
