fix: react-native-macos@0.76+ (#2531)

# Summary

On `react-native-macos` 0.76, `UIGraphicsBeginImageContextWithOptions`
and some other UIGraphics directives were removed so the temporary
solution is to copy the removed functions here.

More details
here https://github.com/software-mansion/react-native-svg/issues/2528
and here https://github.com/microsoft/react-native-macos/pull/2209

Closes #2528

## Test Plan

Built the `fabric-macos-example` for with `react-native-macos@0.76.0`

## Compatibility

| OS      | Implemented |
| ------- | :---------: |
| MacOS   |    ✅      |

## Checklist

- [x] I have tested this on a device and a simulator
