tdf#150020 pptx import: handle algn for outerShdw

Introduces RectangleAlignmentItem that holds a value of the enum
model::RectangleAlignment.

Introduces SDRATTR_SHADOWALIGNMENT that holds alignment for a shadow.

Implements import of algn for outerShdw.

Makes the alignment considered while the shadow is being scaled.
Also adds a unit test that covers this.
