[native] introduce user profile bottomsheet component

Summary:
This diff introduces the ProfileBottomSheet component. When designing this component/how bottomsheets should work in our app, I wanted to take a similar approach to how we currently handle popups/modals in the app today so I created a new screen in root navigator which we will navigate to when the user profile bottomsheet should appear. The "screen" we will navigate to is this ProfileBottomSheet component

Depends on D9098

Test Plan:
Confirmed that I am able to navigate to and back from this new "screen".

I created this test function in RelationshipListItem:

onPressTestNav = userInfo => {
  this.props.navigate<'UserProfileBottomSheet'>({
    name: UserProfileBottomSheetRouteName,
    params: {
      userID: userInfo.id,
    },
  });
};

and got the following:
