Add Advanced Settings switch to Editor Settings

[KoBeWi]

Closes #30866

godot.windows.editor.dev.x86_64_oXfACy2LJL.mp4

Feel free to suggest changes to this list.

Other than that:

• restore_scenes_on_load is no longer marked as requiring restart
• enabled code that makes default value settings not stored

Are you by chance implementing this button partially because of #69012 (review) ?

[KoBeWi]

No, but I can look into integrating that. Maybe after both PRs are merged.

[KoBeWi]

Ok finished.

I noticed editor settings are annoyingly hackish. Customized settings are defined via a set of macros and some of them manually specify restart usage. I'll probably do a follow-up to make it closer to project settings. And then maybe unify the 2 somehow, because there is duplicated code.

Check OP for current settings overview and changes summary.

Needs rebase, then looks good to merge IMO.
