Support native Expo UI for IOS

[johannbuscail]

Hey, the library is really good but I've noticed that it causes many performance issues on my devices (I have an iPhone 16 Pro Max) and I'm not the only one to say this.

Would it be possible to add support for native iOS rendering and keep the current implementation for Android?

Small implementation:

import { Text } from '@⁠expo/ui/swift-ui'

<Text
  modifiers={[
     contentTransition("numericText"),
  animation(
     Animation.spring({ response: 0.4, dampingFraction: 0.6 }),
    TOTAL_SECONDS,
  ),
  frame({ maxWidth: 400, alignment: "leading" }),
]}>{countdownString}</Text>

I think this would be very beneficial to this library, and help making it popular.

Thank you!
