Disable Navigation Page Back Button Long-press Menu

[AaronECS]

Description

There should be an option in the navigation page properties to disable the back button long-press menu feature.

Public API Changes

Add a property NavigationPage.BackButtonLongPress = "True/False"

Intended Use-Case

In my opinion, the long-press feature of the navigation page back button should be disabled by default since it can cause confusion when users try to navigate back to previous pages. Disabling this feature by default and then having a property to enable it would keep the same functionality and improve the usability of applications with navigation.
