SDL_HINT_ENABLE_STEAM_CONTROLLERS defaults to '0' instead of '1'

I'm not exactly sure where to file this issue, as it's not exactly an issue with the steamlink-sdk, and it's not an issue with the public facing SDL repo (AFAIK), but an issue with the custom build of SDL that ships with the steamlink. If there's a better place to file this, let me know @slouken.

Issue: Per SDL_hints.h, SDL_HINT_ENABLE_STEAM_CONTROLLERS should default to '1', enabled. However, as experienced in a native steamlink app, moonlight, it has defaulted to disabled since its inception (user reports track the issue as appearing after build 822, which used an sdl 2.0.17 build, and near as I can tell this hint landed as part of 2.0.22). It defaults to '0', and steamlink native apps on builds after 822 can only see steam controllers if SDL_ENABLE_STEAM_CONTROLLERS=1 is explicitly set as a shell/environment variable.

As far as the public facing SDL repo goes, I can only find three commits which contain SDL_HINT_ENABLE_STEAM_CONTROLLERS, as per git log -p --all -G 'SDL_HINT_ENABLE_STEAM_CONTROLLERS':

• First commit where the hint is documented
• Where SDL_hints.h was sorted alphabetically
• Where it was removed as used in the development of sdl3

Aside from it's presence in SDL_hints.h, there are no commits where it's ever actually referenced/used via SDL_GetHint(SDL_HINT_ENABLE_STEAM_CONTROLLERS), thus I am led to believe it's part of an downstream patchset for SDL maintained by Valve.

You're right, the Steam Link version of SDL defaulted that hint to "0". This is fixed for the next firmware update, thanks!
