Fix animation conversion in versioning

Animation in X and Y channels used `scene->r.xsch` as scene size, which
resulted in incorrect conversion for Y channel.

Fix T88263: Incorrect image offset from old file

Versioning code for converting strip offset property doesn't work, when
property was animated and disabled or when crop was used.

When offset property is animated and offset is enabled, animation is
converted to be used with new transform design. When offset is disabled,
animation is left untouched. New transform design doesn't have option
to disable offset, and therefore old unconverted animation is used
instead of converted static value.

Remove animation from propery if it was unused.
