fix: frame limit out of game uncapped (#5495)

This fixes an issue where the FPS of the main menu and other menus would be uncapped when not in-game, resulting in the main menu being drawn at, say, 2400 FPS. The FPS limit is now capped at the refresh rate, which is also the FPS at which the JCEF client is drawn, giving the appropriate smooth feel without wasting performance on unused frames.
