Description

HybridWebView has no good way to customize how the platform webviews are created.

BlazorWebView has these two methods for that purpose:

• https://learn.microsoft.com/dotnet/api/microsoft.aspnetcore.components.webview.wpf.blazorwebview.blazorwebviewinitializing?view=net-maui-8.0
• https://learn.microsoft.com/dotnet/api/microsoft.aspnetcore.components.webview.wpf.blazorwebview.blazorwebviewinitialized?view=net-maui-8.0

And we should consider similar functionality for HybridWebView.
