[PATCH 6/7] winex11: Always generate fake ConfigureNotify for embedded windows.

[Rémi Bernon]

From: Rémi Bernon

We won't receive a ConfigureNotify event if the embedded window has been
reparented without moving or resizing it. Top-level windows always
receive synthetic ConfigureNotify from the window manager.
