Fixes#21825 by making 'DrawingLocks' which lock only if multi threaded drawing is enabled. Refactors TTF.cpp to use this.
Also cleans up some header files, modernises constants, and removes code to avoid using shared_mutex on MacOS builds. This was originally added because older versions of MacOS didn't support this in the STL.

ImageId struct is 8-bytes large and can fit in CPU register. Passing it
by value lets compiler pass it in register instead of forcing to
reference it from memory.
In my tests this brings
[dome park](https://github.com/OpenRCT2/OpenRCT2/files/6134362/dome-export.zip)
benchgfx results from 42.16s down to 41.08s, or by 2.5%.
