chore(iOS): add RNS_IPHONE_OS_VERSION_AVAILABLE macro (#3171)

## Description

Adds `RNS_IPHONE_OS_VERSION_AVAILABLE` macro in order to simplify SDK
checks in native iOS code.

### Before
```obj-c
#if defined(__IPHONE_OS_VERSION_MAX_ALLOWED) && defined(__IPHONE_26_0) && \
    __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_26_0
// ...
#endif 
```

### After
```obj-c
#if RNS_IPHONE_OS_VERSION_AVAILABLE(26_0)
// ...
#endif
```

Closes
software-mansion/react-native-screens-labs#286.

## Changes

- add `RNS_IPHONE_OS_VERSION_AVAILABLE` macro
- replace old SDK checks with new macro
- remove outdated SDK checks (iOS 14, iOS 15; min target is 15.1)

## Test code and steps to reproduce

Example apps should build on both architectures.
