Compositor: Full frame distort nodes

Adds full frame implementation to "Displace", "Crop", "Flip",
"Plane Track Deform", "Corner Pin", "Movie Distortion",
"Lens Distortion" and "Map UV" nodes.

The other nodes in "Distort" sub-menu are implemented
separately in other commits.

No functional changes.

Part of T88150.
