fix: ifdef orientation code that requries iOS 16 (#1794)

## Description

Currently when XCode w/o support for iOS 16 is used the RNSScreens
compilation will most surely fail due to unrecognized symbols being
present in the `RNSScreenWindowTraints` code.
See [this
discussion](#1732 (comment)).

## Changes

Added compilation guards for iOS sdk version. When not present old
implementation is used.


## Test code and steps to reproduce

See #1732 & try to compile & test on different major versions of xcode
(e.g. 12 & 14)

## Checklist

- [ ] Ensured that CI passes
