Custom Avalonia Themes developed by Devolutions

MacOS Theme [Work in Progress]

(Inspired by @MikeCodesDotNET's earlier draft)

This theme is currently based on Avalonia.Themes.Fluent, both as a fallback for any controls not covered yet and as starting point for our (somewhat simplified) style definitions targeting AppKit macOS look.

While we are prioritizing controls for Devolutions Remote Desktop Manager initially, the goal is to create a theme that helps all of the Avalonia community to bring a native look to their macOS apps.
