tdf#123569 correct position of rotated Writer image

Error was, that the position pFrameFormat->GetHoriOrient().GetPos()
was treated as left/top of snap rectangle and the associated left/top
of a logic rectangle was calculated from it based on rotation angle.
But actually it is already left/top of logic rectangle.
Nevertheless effectExtent has to be calculated for the rotation.

The fix is based on commit 3262fc5ef3bde5b158909d11ccb008161ea95519.
A direct backport to LO7.2 is not possible.
