[Catalyst] WebView does not display ContextFlyout on right-click

[kubaflo]

Description

The ContextFlyout property does not work with WebView. When a MenuFlyout is assigned to the ContextFlyout of a WebView, it never appears on right-click. This works as expected on other controls, but WebView ignores it entirely and overrides it with its own implementation.

You can see this bug even in the Maui Controls sample App

Steps to Reproduce

maui/src/Controls/samples/Controls.Sample/Pages/Core/ContextFlyoutPage.xaml

Lines 127 to 135 in 2f80167

	<WebView x:Name="ContextMenuWebView" Source="https://bing.com" MinimumHeightRequest="400">
	<FlyoutBase.ContextFlyout>
	<MenuFlyout>
	<MenuFlyoutItem Text="Go to MAUI repo" Clicked="OnWebViewGoToSiteClicked"></MenuFlyoutItem>
	<MenuFlyoutSeparator />
	<MenuFlyoutItem Text="Invoke some JS" Clicked="OnWebViewInvokeJSClicked"></MenuFlyoutItem>
	</MenuFlyout>
	</FlyoutBase.ContextFlyout>
	</WebView>

<WebView x:Name="ContextMenuWebView" Source="https://bing.com" MinimumHeightRequest="400">
