Summary

Extend the Plugin.Maui.ZoomView library to support the Windows (WinUI) platform, so that ZoomView works on Windows in addition to Android and iOS.

Motivation

• Many .NET MAUI applications target Windows.
• ZoomView is currently only available on Android and iOS, limiting cross-platform scenarios.
• Adding Windows support will make the plugin more valuable to developers and improve user experience for Windows users.

Requirements

• Implement a ZoomView control for the Windows (WinUI) platform, following the current cross-platform API of Plugin.Maui.ZoomView.
• The Windows implementation should provide zoom, pan, and reset functionality similar to Android/iOS.
• Ensure the control supports common content types (images, layouts, etc.).
• Use recommended WinUI or UWP controls and patterns for gestures and transformations.
• Add platform checks and multi-targeting as needed for MAUI compatibility.
• Update all relevant documentation and usage samples.

Acceptance Criteria

• ZoomView works on Windows with a similar feature set as other platforms.
• No breaking changes to the existing API.
• Automated tests or sample pages demonstrating Windows support are included.
• Documentation describes Windows support and any platform-specific notes.
