fdo#74772 : File Corruption - Issue related to List Bullet Numbering

- A File containing a graphic shape bullet is captured as a numPictBullet in
  MS office[in numbering.xml].
- Currently LO has support for graphic bullet as Image. Graphic bullet as Shape
needs to be preserved in LO.
- Since the numPictBullet is not exported in LO, but in <abstractNum>
<lvlPicBulletId> was exported which lead to corruption.
- Fixed the corruption caused due to lvlPicBulletId.
- However the shape is not getting retained. Need to add implementation
for gprahic bullet as a shape.
