Proposal: TabViewItem should respect CornerRadius API

Summary

To set the corner radius of a TabViewItem, developers today have to override the OverlayCornerRadius resource. They should also be able to use the TabViewItem.CornerRadius API for that.

Example

<muxc:TabView>
    <muxc:TabView.TabItems>
        <muxc:TabViewItem Header="Tab 1" CornerRadius="0">
            Some tab content
        </muxc:TabViewItem>
    </muxc:TabView.TabItems>
</muxc:TabView>

Additional Context

This proposal is related to a few other TabViewItem issues like https://github.com/microsoft/microsoft-ui-xaml/issues/3047 and https://github.com/microsoft/microsoft-ui-xaml/issues/2653. @stmoy FYI

研究方向: Examine the existing TabViewItem template in the WinUI repository (e.g., 'TabViewItem.xaml') to understand how 'OverlayCornerRadius' is currently applied. Look at similar controls like 'Button' or 'Border' that already expose a 'CornerRadius' property for API consistency. Review linked issues #3047 and #2653 for additional context on TabViewItem customization. Check if there are any existing PRs or discussions about adding this property.
