Reanimated 120 fps (#2636)

## Description

This PR adds support for 120 fps on iOS devices. On Android, 120 fps is already supported without any changes.

## How to enable 120 fps mode in your app

### Android

There's nothing to do. Just make sure that your device has 120 fps mode enabled in the general system settings.

### iOS

Add the following lines to `Info.plist` of your app:

```diff
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	...
+	<key>CADisableMinimumFrameDurationOnPhone</key>
+	<true/>
</dict>
</plist>
```

Once added, it should be visible Project Settings > Info > Custom iOS Target Properties:

If it's not, then restart Xcode. Finally, build and run your app as usual.

## Example

<summary>FpsCounter.tsx</summary>

```tsx
import Animated, {
  runOnUI,
  useAnimatedStyle,
  useSharedValue,
  withSpring,
} from 'react-native-reanimated';

import React from 'react';
import { View } from 'react-native';

export default function FpsCounter() {
  const [state, setState] = React.useState(false);

  const x = useSharedValue(0);

  React.useEffect(() => {
    runOnUI(() => {
      'worklet';
      global.frameTimestamps = [];
    })();
    x.value = withSpring(state ? 360 : 0);
  }, [state]);

  const handlePress = () => {
    setState((state) => !state);
  };

  const styles = useAnimatedStyle(() => {
    if (_WORKLET) {
      const now = _frameTimestamp;
      global.frameTimestamps.push(now);
      if (global.frameTimestamps.length >= 20) {
        const first = global.frameTimestamps.shift();
        const fps = (1000 / (now - first)) * global.frameTimestamps.length;
        console.log(`${fps.toFixed(3)} fps`);
      }
    }

    return {
      transform: [{ rotate: `${x.value}deg` }],
    };
  });

  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <Animated.View
        style={[{ width: 200, height: 200, backgroundColor: 'red' }, styles]}
        onTouchStart={handlePress}
      />
    </View>
  );
}
```
