* Cleanup and reorganise playground app

* Separated tests into three categories
  1. Layouts - layout specific tests and feature showcase
  2. Options - options related tests; interactions between static and dynamic options, merge options etc
  3. Navigation - general navigation features; Orientation handling, events, Overlay etc

* Fixed a few Android bugs
  1. testID wasn’t applied on TopBar react buttons
  2. static options were disregarded when creating initial BottomTab options
  3. Trying to open a none existent SideMenu would result in a crash

* Fix e2e tests

* Fix lint

* Few fixes + split push from SideMenu test into two tests

* Fixes e2e

Until now controlling drawers touch gestures was impossible, drawers received gesture opening touch from the entire screen and that causes collisions with other gestures (which are implemented on the javascript side).

This commit adding modes for how sideMenu drawers gestures will receive opening touch.
```
{
  sideMenu: {
    openGestureMode: 'entireScreen' | 'bezel'
  }
}
```

- `entireScreen`: drawer gesture will trigger drawer opening from the entire screen
- `bezel`: drawer gesture will trigger drawer opening only from the center screen bezel frame

The default didn't change.
