Fluent2: ListViewItem/ListBoxItem Has Hardcoded Padding

[robert-abeo]

Description

The DefaultListViewItemStyle (ListBoxItem, etc.) have hardcoded Margin/Padding. These are some of the most important properties to customize and should NOT be hard-coded. That said, this is an issue in upstream WinUI as well.

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

Lines 22 to 23 in fcab981

	<Setter Property="Margin" Value="0,0,0,2" />
	<Setter Property="Padding" Value="16,0,12,0" />

Reproduction Steps

See Fluent Theme

Expected behavior

Lightweight styling resources should exist for these properties as in other controls:

ListViewItemPadding at minimum.

Actual behavior

Re-templating is required to adjust padding of ListBoxItems/ListViewItems.
