Isolate irrlicht references and use a singleton (#6041)

* Add Device3D class which will contain IrrlichtDevice interface move getSupportedVideoDrivers to Device3D Add Device3D singleton & use it in various places Rename Device3D to Rendering engine & add helper functions to various device pointers More singleton work RenderingEngine owns draw_load_screen move draw functions to RenderingEngine Reduce IrrlichtDevice exposure and guienvironment RenderingEngine: Expose get_timer_time() to remove device from guiEngine Make irrlichtdevice & scene manager less exposed * Code style fixes * Move porting::getVideoDriverName, getVideoDriverFriendlyName, getDisplayDensity, getDisplaySize to RenderingEngine Fix XORG_USED macro -> RenderingEngine + create_engine_device from RenderingEngine constructor directly * enum paralax => enum parallax
