fix(Android): Fix calculating header height when changing status/acti…

…on bar visibility (#1922)

## Description

Currently when user changes status bar and action bar visibility header
height is not being changed on `use(Re)animatedHeaderHeight`. This PR
fixes this by checking if status bar or action bar has been hidden.

## Changes

- Fixed calculating header height by taking into account status bar
height and action bar height.

## Test code and steps to reproduce

You can check how those change works by changing `statusBarHidden` /
`headerShown` in Test1802.tsx test.

## Checklist

- [ ] Included code example that can be used to test this change
- [ ] Ensured that CI passes
