Refactor Game class (part 2) (#5422)

* showPauseMenu is now part of game
* remove many flags parameters passed to game functions, use the member.
* rename VolatileRunFlags to GameUIFlags (this will permit to share structure with client and CSM
* updatePointedThing: remove pointer ref, we already have the pointer in rundata
* move some attributes outside of VolatileRunFlags after renaming, to game class
* rename statustext to m_statustext
* make some const variables static
* All those changes permit to reduce a little bit function class cost and will permit to interface CSM with some interesting Game flags
* Expose GameUIFlags to client
* Client now have GameUIFlags parameter and setters for other classes
* Fix minimap show/hide in Lua because we now have access to the real flag
