[PATCH v3 3/4] d3d8/tests: Avoid creating visible windows concurrently.

[Rémi Bernon]

From: Rémi Bernon

This causes a foreground window race condition and will cause spurious failures
depending on how pending X11 events are processed concurrenly.

Some tests now fail consistently and more todo_wine are needed.
