Refactor/2318/migrate pre render service 2

[shaman-apprentice]

• migrate codeMap.preRender.service
  • explicit state actions on which to render
  • add throttling
  • reduce total initial calls to render of default dev map from 58 to 1
  • I did no performance measurements, but I am pretty sure it is not slower than before
• fix loading indicators (#2977)
• delete code for re-selecting building after map change as this didn't work and wasn't missed

@shaman-apprentice is it intentional that this is still a draft? I guess so as there are still some open ToDos?
