Windows: fix window resizing with decorations disabled

[tymmesyde]

Fixes #4186

This fixes the client area preventing the window to be resized while decorations are disabled.
This is still not perfect, the top border of the window has a resize area shorter than normal windows because of the titlebar that needs to be hidden.

let window_attributes = WindowAttributes::default()
     .with_decorations(false)
     .with_resizable(true)

• Tested on all platforms changed
• Added an entry to the changelog module if knowledge of this change could be valuable to users
• Updated documentation to reflect any user-facing changes, including notes of platform-specific behavior
• Created or updated an example program if it would help users understand this functionality

I did something similar in #4181. But I found that we all have a problem: The border calculation logic of Windows10 and Windows11 is different.

I found this in tao's source code.
