FPS Limiting in sway

[dhofer]

Wolf currently sets the environment variable GAMESCOPE_REFRESH to maxFPS from the Moonlight client.
To have something similar in the new default sway setup we could set DXVK_FRAME_RATE to the same value. This would allow automatic FPS limiting in DXVK and recent versions of VKD3D.
