Using ContentPresenter as ListViewItem template is not working

[Arlodotexe]

Current behavior

Nothing is rendered

Expected behavior

Items should render the same as it does on UWP.

How to reproduce it (as minimally and precisely as possible)

On a ListView, set the item container style to:

<ListView.ItemContainerStyle>
    <Style TargetType="ListViewItem">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ListViewItem">
                    <ContentPresenter />
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ListView.ItemContainerStyle>

You're running afoul of this issue: #857

The workaround is to explicitly bind the Content and ContentTemplate on the ContentPresenter:

                            <ControlTemplate TargetType="ListViewItem">
                                <ContentPresenter Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}" />
                            </ControlTemplate>

                            </ControlTemplate>

@davidjohnoliver So this fixed our issue on WASM, but it also causes a crash on UWP when the debugger isn't attached, somehow.

Had trouble using platform-specific code in the style setters, so we'll have to just remove the template setter for now.
