Xamarin.forms: GTK: ListView entries are handled as XML internally; this conflicts with the other platforms

[tluyben]

Description

As ListView string items are handled as XML, illegal characters for XML will not render. This is fine but is incompatible with the other platforms.

Of instance strings with < > etc won't be rendered and generate a Gtk-WARNING as they should be &lt; &gt; etc

This is contrary to the other platforms so I would label it a bug.

Steps to Reproduce

1. Create a ListView with an item "< Back" in Platform.GTK
2. Run application

Expected Behavior

A row showing "< Back" rendered and clickable.

Actual Behavior

An empty row "" rendered and clickable.

It is the Pango markup (excuse my ignorance); it does behave completely difference than other platforms so it would probably be better to switch that off if possible.
