[Feature] Option to override the display refresh rate

Browse source 
This adds a per-game graphics option, `DisplayRefreshRate`, to override the display refresh rate.

It defaults to 60 Hz, and is located in Dev tools.

Games using variable timesteps benefit from higher refresh rates.

Closes #19319
