Description
Describe the bug
DataGrid的Template里面的两个Margin硬编码有问题。DataGridBaseStyle和DataGrid.Small都受这个影响。
Steps to reproduce the bug
给header换个颜色就能重现了。
<DataGrid.ColumnHeaderStyle>
<Style TargetType="DataGridColumnHeader">
<Setter Property="Background" Value="Blue"
</Style>
</DataGrid.ColumnHeaderStyle>
下面这两个Margin="0,0,0,6"会让header下面出现gap，当Header的背景色都是灰色的时候看不出来，但是换了颜色后，就很明显了。第一行和Header之间有个灰色的gap。
<hc:SimplePanel Margin="0,0,0,6" ...
<DataGridColumnHeadersPresenter x:Name="PART_ColumnHeadersPresenter" Margin="0,0,0,6" ..
Expected behavior
换header颜色时，下面不要有灰色gap

Research direction
Search the DataGrid template for DataGridBaseStyle and DataGrid.Small, then inspect the SimplePanel and DataGridColumnHeadersPresenter margins shown in the issue. Reproduce the problem by applying a blue header background. Done means the header background reaches the first row without the visible gray gap in both affected styles.
