[Suggestion] Finally use the share button on PS4/PS5/Switch/XSX controllers for screenshots and saving instant replays

[KingKrouch]

This is the one thing that I feel like controller support has been lacking on Steam, and for some reason, I constantly have to adjust this on a per-game basis alongside enabling the built-in deadzone option (as for some reason it's disabled by default, even if you need it outside of hall effect joystick controllers) because SteamInput's default setup kind of stinks.

Please consider making this more consistent with current-gen consoles, where pressing the share button will trigger a screenshot, but pressing and holding will save an instant replay. I can understand Steam using chords for older controllers, but there's really no good excuse/justification for not having this functionality outside the Xbox 360, PS3, Xbox One, Steam Controller, and Steam Deck controllers. In the case of PlayStation 4/5 and Switch controllers, the share button is being used for other things, when at least on the PS controller, the trackpad is universally used as a select button on console releases of games.
