tdf#55058 tdf#141982 EMF: Add rotation and path support for RECTANGLE record

Previous implementation of EMR_RECTANGLE, doesn't support rotation
and EMR_RECTANGLE was not work with EMR_BEGINPATH, EMR_ENDPATH and EMR_ABORTPATH

The EMR_BEGINPATH opens path bracket construction.

Once path bracket construction is open, an application can begin specifying records to
define the points that lie in the path. Path bracket construction MUST be closed by an
EMR_ABORTPATH or EMR_ENDPATH record.

With this patch all these issue was resolved for EMR_RECTANGLE
