[macOS] Saving - Add per core name for Saves/States option

[shasen1235]

First I want to congrate we are finally on AppStore. This is really a dream come true and belows are some of my experience so far.

I tried cloud sync to my home NAS and things are working great. Just macOS version RetroArch seems missing saving Saves/States to core name folder. For example - PPSSPP iOS: With option on, saves to PPSSPP folder, with option off, saves to root folder macOS: Saves to root/PSP folder

For now it seems no configuration will let both platforms sync to one shared fold. Windows version may be either way, gotta check it later.

In addition, can we also add "Save state" as a trigger to initiate cloud sync? Sometimes when I finish playing, I just save state then close the app. But this way it won't trigger cloud sync immediately, and if I launch from another device now it won't have my current save state. I know we can trigger it by closing content, but it is just not that strait forward.

Also, is it possible to separate or add individual save box for "Auto save" saves? I understand we have option to auto +1 slot for each auto save. But when using auto save, I prefer it as an safe guard option in case I forgot to save. But I don't want it to be blended into my manual saves. When they are in the same area, it is hard for managing.

Overall, the iOS release is a big success I can say. Emulator games are one of the biggest missing piece I missed since switching from Android. Great jobs!
