[Windows] The application starts together with the console if the release build is used

As a quick fix, I use several linker flags:

```swift
  linkerSettings: [
      .unsafeFlags([
          "-Xlinker", "/SUBSYSTEM:WINDOWS",
          "-Xlinker", "/ENTRY:mainCRTStartup"
          ],
          .when(platforms: [.windows])
      ),
  ]
```

It seems to work, but maybe something else is needed or a different solution. I'm no expert
