Need a fake implementation of POWRPROF.dll.PowerSettingRegisterNotification for compatibility with Special K mods

Special K has a lot of integration with power management on Windows to help with low-end systems. It has been a part of Special K for many years, so there are versions of Special K used in mods 5+ years old at this point that require this API.

I cannot go back and retroactively add compat hacks into all my old mods to make them work with WINE, so I really need the compat hack burden to be placed on Proton's shoulders. Newer versions actually detect WINE and start to disable these features, but I need Proton to do some of the work to make Tales of Vesperia Fix, etc. compatible with SteamDeck.

As I understand things, WINE doesn't implement much of any of the power management APIs in Windows, so there should be absolutely no harm in implementing a stub that just lies to my software and claims to have registered a notification.

Start by locating Proton/Wine implementations or entry points for POWRPROF.dll and related power-management APIs. Check how PowerSettingRegisterNotification is exposed and how compatibility stubs are tested. Done means Special K's registration call succeeds under Proton without requiring actual power-management behavior.
