R108:6724955a7624: [qpa] Always keep a at least one screen
Summary

Qt does not like having no screens. Both Qt XCB and Wayland QPAs have
systems pretend there's always at least 1 screen
present.

Kwin already uses a dummy screen on startup, this patch reinserts the
dummy screen if the platform states that all real screens are removed.

BUG: 399564
