Subject: [PATCH] Related: tdf#129916 svx: clean up duplicated matrix decompose
 for shadow size

Pass the object's transform matrix to createEmbeddedShadowPrimitive(),
this allows decomposing it only at a single place. Also, this will allow
creating the shadow based on the object size.

(cherry picked from commit 4ba368a3dd793bdc703858f358e1af7112decadd)
