feat: add show/hide methods

[sq-tupai]

Hi there, I'v add two methods to control the native view's visibility on Android, it aims to solve the native map view overlapping issue in navigate between pages which all contain maps component.

With these two methods, in Ionic react page, we can hide the native map before leave, and show it before enter.

useIonViewWillEnter(() => {
  map.current?.show().then(() => {
    console.log('map visible');
  });
});

useIonViewWillLeave(() => {
  setLocationId(undefined);
  map.current?.hide().then(() => {
    console.log('map invisible');
  });
});
