Fix darwin/Foundation/NSScreen type property bindings (#6038)

This commit updates the `darwin/Foundation` package's `NSScreen` bindings
to treat Objective-C "type properties" as class methods rather than
instance methods.

As a result, we can now access these properties like this:

```odin
import NS "core:sys/darwin/Foundation"

main :: proc() {
  NS.Screen.mainScreen()
}
```

instead of this:

```odin
import NS "core:sys/darwin/Foundation"

main :: proc() {
  (^NS.Screen)(nil).mainScreen()
}
```

This commit also adds a binding for `NSScreen`'s `screensHaveSeparateSpaces`
type property, which was previously missing from the `darwin/Foundation`
package.
