Add support for per-application settings of the overlay feature. The overlay currently doesn't work with all full-screen applications and games and can even go as far as causing issues when enabled, Assassin's Creed: Valhalla is one such application, the overlay doesn't show up at all, possibly due to Ubisoft anvil's built-in performance overlay. When I tested benchmarks with the game no overlay would display with NZXT CAM overlay enabled, when disabled and using mini-mode I was able to successfully run the benchmark with the in-game performance overlay open.
