avmedia: implement video crop support in the ODP filter

And also import/export the video preview as well. The naming follows the
style used for table shape previews.

The preview is important, since the cropping is relative to the bitmap's
preferred logic size.

(cherry picked from commit cbc6e67d3c88fb6ae39c304604a98eaa504f19cc)
