Keep ScreenOverlays in std::vector, but do not erase elements in the middle and invalidate them instead. Record free indexes in a helper stack. When creating a new overlay, first check for the recorded free indexes. Overlay's type now equals storage index. This speeds up both creation/deletion of overlays, and their access. Removed the gap between "fixed" overlay types and custom ones, to save space. If we ever need more special overlays, these could be created as custom and their ids saved in a variable (similar to how background speech works). Previously present special overlay types are left for backwards compatibility (and to simplify the transition). From upstream f7d2f162fa55aa1b6f37195d890ebe047a204154
