Tracking: Image from Plane Marker operators

There are two operators added, which are available via a special
content menu next to the plane track image selector:

- New Image from Plane Marker
- Update Image from Plane Marker

The former one creates an image from pixels which the active plane
track marker "sees" at the current frame and sets it as the plane
track's image.

The latter one instead of creating the new image data-block updates
the image in-place.

This allows to create unwarped texture from a billboard from footage.
The intent is to allow this image to be touched up and re-projected
back to the footage with an updated content.

Available from a plane track image context menu, as well as from the
Track menu.
