Make Toolbar public

[NXDMN]

Description

I would like to be able to access page's Toolbar

Public API Changes

var toolbar = (this as NavigationPage).NavigationPageToolbar;

Intended Use-Case

In my app (Android) I need a modal page wrapped in NavigationPage to have a back button, but im not using Shell and I have tried with FindViewById(Resource.Id.navigationlayout_appbar), but that way the toolbar i get is from the page before the modal page. Or is there any other way to get the modal page toolbar
