Steam Deck Client Beta Update: External Display Safe Mode, and Steam Input

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.

General:

• Added External Display Safe Mode to developer settings. When enabled, the next time an external display is plugged in Steam Deck will pick a low resolution + refresh rate configuration, which may help in some cases where the external display has issues.
  

Steam Input:

• Restore the previous behavior of using stick deflection rather than the capacitive sensor for Radial Menus that don't have center buttons bound
  
• Fixed an in-game crash
