Steam Deck Client Beta Update: External display settings and more

Note: This update is for the Steam Deck Beta and Preview channels, and includes new features that are still being tested. You can opt into this in Settings > System > Steam Update Channel.

External display settings

• Keep track of refresh rate and FPS limit settings independently for internal and external displays.
  
• Disable refresh rate switching via the quick access menu for external displays by default. Alternative refresh rates are still accessible via the resolution dropdown in Settings->Display.
  
• Added a toggle to developer settings to re-enable refresh rate switching in the quick access menu for external displays. Please note that the Steam Deck’s built-in display was validated to support the full range of refresh rates available in the slider, but for arbitrary external displays we can't provide a guarantee that the resolution + refresh rate combination will be functional. This can lead to a scenario where the external display doesn’t display an image, so there isn’t an easy way to undo the change. Here be dragons, we don't recommend turning this setting on.
  

General

• Performance improvements when rendering the homescreen.
  
• Fixed a crash when loading some SteamInput configs.
  
• Reduced occurrence of double-activations on Soft Press on Touch Pads and Sticks.
