Fluent2 ListBoxItem Style (Et al..) Missing Bindings in ControlTemplate

[robert-abeo]

Description

There are a lot of default styles that don't set template bindings correctly. I give an example for ListBoxItem below but there are other similar cases:

wpf/src/Microsoft.DotNet.Wpf/src/Themes/PresentationFramework.Fluent/Styles/ListBoxItem.xaml

Lines 26 to 29 in d21766c

	Margin="0"
	Padding="{TemplateBinding Padding}"
	Background="Transparent"
	BorderThickness="1"

Should be:

<Border
  x:Name="Border"
  Padding="{TemplateBinding Padding}"
  Background="{TemplateBinding Background}"
  BorderThickness="{TemplateBinding BorderThickness}"
  CornerRadius="{TemplateBinding Border.CornerRadius}">

The Background/Border properties should be settable on the control itself and carried through to the template. These should NOT be hard-coded.

Reproduction Steps

See current Fluent2 theme

Expected behavior

Control templates should have all applicable template bindings.

Actual behavior

Control templates are missing several template bindings.
