fix: fix cast in ElectronDesktopWindowTreeHostLinux (#42179)

Browse source 
Fix cast in ElectronDesktopWindowTreeHostLinux

The frame view of the widget is an `ClientFrameViewLinux` instance only
when both `frame` and `client_frame` booleans are set to `true`.
Otherwise it is an instance of a different class and thus casting to
`ClientFrameViewLinux` is incorrect and leads to crashes.

Fix: #41839
