Editing May 30 2023 build

{{legit}}{{db}}
This build mainly has the fix for the vertical elevator door movement, instead of keeping or reverting the old 2016 change like before, I remade the fix to match the horizontal door movement, and so it appears to be working now, this needs testing to make sure nothing breaks.

Skyscraper now reports the number of CPU threads on startup, this was added since I've been playing with multithreading and trying to apply it to the simulator code, but am not having much success so far.

'''Changelog:'''
#Make Console::Write thread-safe using a mutex, this fixes console issues with Ogre running with a multithreaded WorkQueue
#Updated build doc to build Ogre with multithreading turned on (use the defalt option, instead of switching it off)
#Upgraded FMOD sound system
#(for Linux/Mac) build with C++17
#Report hardware concurrency on startup (hardware threads)
#additional mainscreen pointer checks
#Remade vertical door movement fix to match the horizontal door movement code
