Subject: [PATCH] Add option to disable min/max windows buttons

This commit introduces the functionality to disable the minimise and maximise buttons on windows. These options have been added to the `application.WebviewWindowOptions` and integrated in the Windows application logic. Effectively, developers can now control the availability of these buttons in their windows applications.
