[PATCH 6/7] winex11: Handle ConfigureNotify for embedded window separately.

[Rémi Bernon]

From: Rémi Bernon

These windows might have a (foreign) window parent, and we need to move
them relatively to their parent. This uses XTranslateCoordinates to get
relative positioning instead of NtUserMapWindowPoints.
