[Web] Config refactor - update logic and drop class field (#3673)

## Description

This PR changes how config is handled on web, following #3658 it
separates update and set functionality, which allows passing only
relevant, changed fields to update, as opposed to the entire config.
Moreover it removes the config field from `GestureHandler` - adds
necessary fields as class fields, this mimics how config is handled on
iOS / Android and simplifies the code (previously some fields were both
both config and class fields).

## Test plan

The update functionality was tested on the following code.
```ts
import * as React from 'react';
import { Animated, Button } from 'react-native';
import { useSharedValue } from 'react-native-reanimated';
import {
  GestureHandlerRootView,
  NativeDetector,
  useGesture,
} from 'react-native-gesture-handler';

export default function App() {
  const [visible, setVisible] = React.useState(true);
  const taps = useSharedValue(2);

  const gesture = useGesture('TapGestureHandler', {
    onEnd: () => {
      console.log('Tap detected. Required number of taps:', taps.value);
      taps.set(taps.value + 1);
    },
    numberOfTaps: taps,
  });

  return (
    <GestureHandlerRootView
      style={{ flex: 1, backgroundColor: 'white', paddingTop: 8 }}>
      <Button
        title="Toggle visibility"
        onPress={() => {
          setVisible(!visible);
        }}
      />

      {visible && (
        <NativeDetector gesture={gesture}>
          <Animated.View
            style={[
              {
                width: 150,
                height: 150,
                backgroundColor: 'blue',
                opacity: 0.5,
                borderWidth: 10,
                borderColor: 'green',
                marginTop: 20,
                marginLeft: 40,
              },
            ]}
          />
        </NativeDetector>
      )}
    </GestureHandlerRootView>
  );
}
```
