Add back button to web view form

[alzakharenk]

After attempt to sing in with web view we would like to have a top left back button to return back to app

Now only possible solution is override AuthorizationActivity and add back button programmatically, but r8 is blocking it

I would like to have some configuration for this back button visibility or let's have it's always because we are starting sign in from our custom page
