refactor: sync api::Screen getter sigs to upstream ui::Display GetAllDisplays(), GetPrimaryDisplay(), GetDisplayMatching(), and GetDisplayNearestPoint() methods are all const, so make our wrappers const too. ui::Display GetAllDisplays() returns a const reference, so make our wrapper return a const reference too. This avoids creating a new std::vector<display::Display> each time it's called.
